I don’t see that as being the same. And an 8+ year old computer is pretty old. Maybe the latest Mac or windows would work and maybe not, but it’s unrealistic to expect support for something that dated. However, you are still not prevented from using your old computer. You can continue using an older, supported version of Mac or windows or just install Linux. So your analogy breaks down fairly quickly.
A more apt analogy is if the OS manufacturer doesn’t let you use your computer without premium internet access that you must subscribe to through them.
It means it is only 1/3 evil
