It takes a couple minutes to let you farm your data to Sony and then you're done.

So use a throwaway email that was made with a fake name if you're that paranoid.
Seriously, every company at this point is a data company first and a "whatever they're selling" company second. If that bothers you then it started a long time ago before PSN was a thing and you should flood the market with fake data.

I also don't think it's about the data. They pretty much have everything they need on you with your Steam account (probably worth more if you were forced to make one for the game). It's more likely a combination of wanting to boost their active account numbers and wanting to ban people easier. It can be annoying for developers to ban cheaters through Steam so much easier on them to force players to use a different account and ban you that way.
