For me Linux is about freedom. Other systems might be better in UI/UX or performance (e.g. give more FPS in games for NVidia cards), but I remember the times when Microsoft dominated the IT world and it looked scary.

All corporations strive to fragment the market using non-compatible technologies and then to monopolize the market by consuming other fragments.

This strategy failed in the 90s with the arrival of Linux. Although many times I felt like the whole world will become Microsoft/Wintel, I think we barely missed.

Now, corporations are trying to do it e.g. via forcing everybody into the cloud and killing open protocols. E.g. I have several email accounts and I can't gather mail from all of my mailboxes in one application. Situation is even worse with Calendars. I have two jobs and also my own personal calendar server and I can't collect all my calendars in one app also. I have to routinely check Google Calendar, because even though I can add it to my Thunderbird Calendar, moved or canceled events changes are not propagating to Thunderbird. And I can't integrate Microsoft Outlook calendar into my Thunderbird at all.

I really don't want to rely on whims of one corporation. Also, regarding MacBooks: I remember when the touchbar had no alternatives and it is really awful. This is what monopoly means: you have to live with bad decisions. You have to pay absurd money for a piece of cloth or a roller for the desktop case.
