They're so evil for publishing SSO when no one else was willing to allow IG to make the game the way they wanted to.
I highly doubt SCE had no interest in SO. M$ allowed them so own the IP, which is very important to IG apparently. They add a large sum of money to it and convinced them to keep it on their inferior console. Deja vu.
They may have had interest in SSO, but the fact is that they didn't give IG enough money or dev time to make it.
No matter how you look at it, Sony's to blame. They rejected IG's demands which eventually led to them having to rely on MS to release SSO.
Also, as of now, the XBO is cleaarly superior to the PS4 as it has more quality games.
