That aside, everyone can and should decide for themselves just how comfortable they are with programs like these. I signed up for a Sega account, but won't even buy a game that requires me to register an account to play. Other people couldn't care less about the latter and that's their prerogative too.
its also the only way to do things like cross progression. Im all for 3rd party account linking given nintendo, sony, and xbox will never do it themselves (nor would i expect them to).
Its annoying, but you do it one time and never think about it again. Dont see what the issue is, but to each their own.
