This is ultimately a form of collusion and anti-competitive behaviour - practices that we prohibit in other scenarios because we consider them harmful to our society. It's obvious why some large organisations would like more control over our lives. It's not obvious why we should let them have it.
Unfortunately for now it seems our representatives are letting them have it so personally I'm rooting for a snake-eating-its-tail moment as a result of Windows 10 losing support. There will inevitably be erosion of security and support for applications on Windows 10 once Microsoft declares it yesterday's OS - as we've seen with past versions of Windows. This time there is the added complication that a lot of perfectly good hardware can't run Windows 11 - largely because of the TPM/verification issue we're discussing.
So probably a lot of people who haven't moved to 11 yet aren't going to unless their current computer breaks and they get 11 by default when they buy a replacement. If the charts are correct then 11 only recently overtook 10 in user numbers. After all this time and despite all the pressure from Microsoft and the imminent EOL of Windows 10 over 40% of Windows users are still running that version. (https://gs.statcounter.com/os-version-market-share/windows/d...) So how exactly do the big organisations that want to control the client plan to deal with that over the next few years?
Unfortunately unless there is also some sort of intervention to deal with the collusion and market manipulation by vested interests I doubt enough Windows 10 refugees will jump to open platforms when their current devices fail for those open platforms to reach a critical mass of users. If five years from now Windows 10 user levels are negligible and almost all of the former users are now on Windows 11+ by default then the controlled client side probably wins effectively forever. I think it would take something dramatic happening that increased the desktop market share of open alternatives like Linux to say 10+% to avoid this fate. The only likely source of that drama I can see is if Valve's support for gaming on Linux encourages significant numbers of home users to switch and then general public awareness that you don't have to run Windows or macOS increases.
