Just as he's entitled to no longer accept playstation as his main platform users here are also entitled to not accept his decision. Otherwise what's the point of the thread, to be one massive echo chamber? Some people obviously can't accept that.
Except it already has become one massive echo chamber. The OP stated their decision to switch platforms and now all the PS users are coming out with reasons to put down the OP for simply switching platforms. The only ones who are accepting OP's opinion are those who do not have PS4 as their only or main platform of choice.
Quite literally a prime echo chamber.
It really isn't OP's problem though at the end of the day, it's everyone else's for simply being tilted at his choice. They can argue their opinion, but at the end of the day their opinion will never trump or dismantle the OP's because it is their decision and theirs alone to make.
