If Sony were to do this, I'd throw my PS4 and Vita and never buy a Sony product again. Outrageously immoral behaviour.

The activity mentioned in the OP

"I think in this mood in the EU it would be very smart by sony or valve or both to sue Microsoft in europe over their xbox app, it could dissapear and be an optional app for european users. Whats your opinion? I think they could have success."
