“Every app they have purchased is tied to their AppleID. This is the same with Android, any app you purchased is tied to your Google account. If you leave Google, you leave any app you may have purchased. Thus, the ecosystem”

Sorry, but I wouldn’t buy anything from Google or Apple. The “ecosystem” is just another trendy silly made-up PCism, signifying nothing. You’ll be embarrassed you ever used the term a few years from now.
Not at all.
For example, in the Apple ecosystem I enjoy having up to 10 iOS devices on my AppleID or in my associated “family” sharing the same app, at the same time. As I upgrade or replace any device, that device gets those apps for free, as well as any updates for free. I also enjoy a new iOS every year and numerous firmware updates during the year that add functionality that did not exist previously.
For example, I get the Apple iWork suite FREE that now supports collaborative work, and that is a big deal. Naturally iWork both imports and exports files into the MS Office Suite nearly flawlessly. Numbers (Excel), Pages (Word), and Keynote (PowerPoint). All free.
So, is that a ecosystem? Yes it is.
Now let’s add to it. I can make phone calls or FaceTime phone calls from my Mac, iPad or iPhone. Using either my Ethernet WiFi or phone number, seamlessly. I can move files between these devices using AirDrop by simply clicking on the file and telling the device which device I wish it “AirDropped” too. I can relay video from any device to any other device. That is nice. That is the Apple “environment” that is supported across all Apple devices, so that would be a “ecosystem”
