Let’s cover his points and I will show why he is wrong.
“Ubuntu is harder to use.”
Not true. I have used Ubuntu but prefer to use Mint which is simply Ubuntu with a few minor tweaks. It is full GUI point and click drag and drop windows style interface and just as easy to use as windows 7 with almost all the menus, file system, with standard basic features being the same but with additional productive options.
“Requires using command line.”
Not true. The average user can use Ubuntu or Mint and never need the command line at all unless you are doing something technical such as building your own local VPN server and client which the average user will not be doing. Or building something very custom. Or downloading a 3rd party program that only has download instructions for back when Linux WAS primarily command line. But now even almost all of those have been packed up in an installer file download. It is not honest or true at all to try and discourage folks from trying it by painting Linux as a “DOS like command line only” OS. NOT ANYMORE at all, one will never need the command line interface for average normal use.
Won’t run a lot of popular programs and games.
This is not the fault of Linux and will naturally be corrected if MORE folks dumped MS and used Linux. Build a demand and they will come. There are only a very limited number of important programs that are not compatible and this is because the developers refuse to port them to Linux. They have made crooked deals with MS to not port them to Linux.
Replacements for these are available for Linux but no one wants to make time and effort to adapt to them or use other alternatives. They are lazy. And what issues these replacements might have are only still present because of lack of demand or developers would take the time to fix them.
Games... As you say, there are games just as technical and as good as MS games available from steam ported for Linux. But users have THAT ONE GAME they just cannot live without to be rid of MS. They would instead allow themselves to be perpetually abused by MS rather than adopt a similar competitive game ported for Linux. This is the fault of their OWN addiction not Linux.
“Won’t run Android apps.”
Not true. There is Anbox, Genymotion, or Waydroid apps for Linux.
And there is no reason why one can’t have BOTH Linux and MS in the same machine to cure these very limited application issues. Files in a MS volume can even be accessed and manipulated drag and drop/copy and paste to Linux volumes when booted up in Linux.
“I prefer installing Ubuntu Studio myself because it comes with an incredible suite of multi-media tools already installed.”
This is why I use Mint “Cinnamon” version. It comes boxed with about all apps and tools you will ever need in a suite. And it has all kinds of Gnome type graphics customization options. And of course it comes with direct access to the Ubuntu software repository with one click application installs using the software manager or synaptic.
I don’t have a problem with the various forms of Linux. I think that many are absolutely amazing. But as to whether they are as easy to use as Windows depends partially on the hardware you are using, the Linux version, and what you are trying to accomplish.
Linux users make up less than 4% of the desktop and laptop market according to Wikipedia and other sources. It is possible to install Linux on iPads and some tablets and phones. I love a technical challenge and have ventured into this area on occasion.
One of the issues is that for most laptops and desktops the manufacturers and software developers consider Linux to be a niche market. So the drivers especially are often not as well developed. I am going to go off on a little bit of a tangent here, but touchpads provide a fairly good example.
I am finicky about touchpads, but with a laptop you are basically just stuck with the one that comes with it. Tapping, scrolling, zooming and multi-finger operations can become a complete nightmare with a bad driver. Of course, the absolute worst drivers come with Bluetooth keyboard/touchpad combos but that is another story.
On my laptops with Windows 10 and 11, usually just the stock drivers work very well and are a pleasure to use. But I never have found a touchpad driver for Linux that really makes me happy. And I am not even referring to tapping, scrolling, zooming and multi-finger operations. Just moving the pointer around the screen typically doesn’t work as well.
If you turn the sensitivity up to the point where it is easy to get the pointer precisely over what you want to select or click on then you have to reposition your finger multiple times to get it across the screen. And holding one finger on the touchpad so that you can scroll or select text often causes the screen to be inadvertently zoomed in and out. Using better techniques such as two finger scrolling can help, but not when you are selecting text or using a photo editing program.
Somehow these very basic controls are difficult enough in my Linux setups that it is typically far easier to use a mouse which is not always convenient... Sometimes this is not much of an issue depending on the hardware or the Linux build. But most of the time it is. And that is a mundane difference that is a little difficult to explain but can make a huge difference in the user’s experience.
This is the type of thing that gives one the feeling that Linux is not as refined as Windows. I have been using computers since long before graphical interfaces became the rage; using a command line does not really bother me. But a bad touchpad driver can cause a lot of frustration depending on what you are trying to accomplish.
