No, the adapters are not 10 years old (more like 2) but there are drivers for such that go back as far as Vista.
" BTW, it's the legacy support for everything that keeps Windows from being as good of an OS as Mac and Linux."
Rather, as Linux forums well attest relative to the small percentage of Linux users, it is the lack of compatibility in Linux, plus the lack of comparable software for customization (without learning to code), that keeps Windows from being as good of an OS as Windows.
It makes zero sense that anyone would write drivers for an OS that isn't even supported by its vendor (Microsoft) for a two year old adapter.
You may have purchased that adapter two years ago, the likelihood that it was designed, engineered and produced much longer ago than that is evident, IMO.
Combined with the fact that your adapter's maker doesn't appear to make a driver for it should tell you its incompatible with Linux. I don't understand why you're complaining if you have a piece of hardware that you know isn't compatible with Linux?
You may as well be complaining that your USB wi-fi adapter isn't compatible with a Commodore 64.
Edit, “that keeps Linux from being as good of an OS as Windows” for the desktop. But mobile devices help show what could be done if focused a few distros and without restrictions of GNU licensing, as helpful as that is.
I think you meant to say "keeps Linux from being as good of an OS as Windows."
That said, Linux isn't for everyone. No one denies that. Linux has its use cases the same way Windows has its use cases.
If you're an end user who wants to plug in a device and have it "just work" chances are you're buying a Mac.
If you're an end user who needs to use software that's primarily Microsoft based and have a relatively recent computer and peripherals, then you're going to go Windows. It actually does a pretty decent job keeping most hardware drivers up to date with the most current OS though there are times hardware will stop working because that device's manufacturer stopped supporting the device and creating drivers for it. (I have a printer and webcam that fit into this category.)
If you're an end user capable of doing some minimal code, or an engineer such as I am and need to perform engineering specific tasks using customized software and code then chances are you're going Linux.
BTW, the Canon Printer and Logitech USB Webcam above that Windows no longer supports as of Win10 are perfectly supported and functional on my Ubuntu Linux 21.04 desktop. Go figure.
