In this case, Windows 10 will continue to run on your computer perfectly fine. Microsoft are not changing anything about Windows 10, or the way people use Windows 10, or removing any Windows 10 'ownership' that people have right now.
The complaints are that Windows 11 has additional requirements (a modern CPU with a TMP 2.0 chip), and that older computers don't have that. Essentially people are sad that they can't upgrade because their computers don't meet the minimum spec. TMP (https://en.wikipedia.org/wiki/Trusted_Platform_Module) is a bit controversial, but you can run Windows without it. Just not Windows 11.
