The funny thing to me is that a throwaway Sony account seems more likely to make a future intentional use of Sony’s services a hassle.
You can’t make the account because that email is already in use. You do the “forgot my password” thing. You notice that the account’s name is terrible, and now you’ve spent more time fixing a worse thing than if you just didn’t have an existing account at all.
Or you make a new account with a new email. Making the God of War account a useless little mole on your library.
I’d call it an appendix, but unlike forced account creation for single player games, the appendix has actually been proven to have a legitimate purpose despite its shortcomings.
As a shareholder I would be pretty hard against this kind of shit that do nothing positive but hurts PC sales.
