Windows 10 end of support on Surface Studio

I've searched this forum but couldn't find any comments on this. Am I the only one that is really angry?
I bought a Surface Studio from a Microsoft Store in 2019 for the princely sum of just over $4,000, the most expensive PC I've ever bought. Only five years later and today I received the anticipated notification that Windows 10 is soon to go 'end of support' and a reminder that my PC *still* is capable of upgrading to Windows 11. 
How is it possible that Microsoft made the decision to leave their own hardware behind when they created Windows 11? I have always argued that the renowned Apple stability is due to the fact that they make both the hardware and the software, but apparently Microsoft don't care about their own hardware. The warning, incidentally, came will the helpful suggestion that perhaps I should replace my PC with something capable of running Windows 11. I can tell you what that *won't* be.
Anyone else out there in this position?
