Is it? Windows has always had an extended support life cycle if ten years, and Windows 11 is heavily criticised for their new restrictions on hardware. I've seen Windows 10 run just fine on budget devices that go further back than that.
You can get the most recent Ubuntu LTS to run on a ten year old Thinkpad without issue. The performance may be limited bytthe hardware, but the software isn't the problem here.
Honestly, if I were to pay the premium prices Apple asks for their products, I'd expect them to outsupport a bunch of hackers that had nothing to do with the hardware.
