The requirement for TPM for Windows coincides with demands by government's worldwide to increase surveillance on online activities of user. Apple devices already have those, and looks likes they are already baking the government mandated surveillance into their OS too - <a href="https://twitter.com/matthew_d_green/status/1423071186616000513" rel="nofollow">https://twitter.com/matthew_d_green/status/14230711866160005...</a> ... (Windows has it easy here as it is already a spyware platform, and doesn't try too hard to hide that fact). So it looks like Microsoft's trying to catch up to Apple on the hardware side, and Apple is trying to catch up with Microsoft on the software side - all to better spy on their users. (But ofcourse, it's all in the name of protecting "your" security and to protect "children" /s).
