So use buggy Catalina or BigBrother privacy broken Big Sur great options.. By the way, I saw about macs with T2 always encrypted stuff, just never tested like if there is no password set (via FileVault enabled by user), then it works like a bitlocker Windows disk on a laptop with TPM ? One thing to note is that breaking the seal in this way seems to disable Apples FairPlay DRM, so you cant access anything protected with that until you have restored a sealed system.
