That's IMO a big part of what's different between the 7 transition and this one. Last time Microsoft was going around upgrading people's computers for them, and even if people didn't want to jump to 10 right away, they allowed Win 7, 8, and 8.1 keys to activate it pretty much whenever. Now with their hardware requirement, they're official line is telling people without TPM that their hardware is junk when they stop supporting Win 10. That drove people to look for the better alternative Microsoft won't tell you about.

The TPM2 requirement is purely to drum up sales for hardware vendors and ensure that they keep bundling Windows with their machines.
