I really can’t, for anyone who considers themselves tech savvy. At this point it isn’t “some specific apps run great and the rest is a hassle”, but the other way around: some specific apps are a hassle but the rest runs great. Sure, you should do a bit of research if your usecases are already ‘solved’, if you want to do an all-or-nothing switch. But you can also do a dual boot, if there really ends up being something that isn’t solved on linux.
I just keep getting surprised with how little people apparently care about their privacy.
