Debian user here. All people have a doorkey. Some people have an alarm system as well. Infosec is about ' what do you have and what do you know '. So in principle TPM is a defencible argument. You should absolutely bail from MS products for different reasons. Like privacy. Your PC isn't yours anymore. Your NPU will reduce THEIR costs. Etc.
Don't enter Linux thinking its a drop in replacement. Go slow and do 'ships in the night'. Move data over to the new ship. Start embracing OSS on windows, it'll be familiar when you finally bail. G luck.
