Speculation leads to suggestions, which leads to a better game. What your saying to me is that our opinions don't matter and any critique is wrong.
I'm saying that you don't have the technical perspective to offer meaningful technical advice. Telling me that shipping my game on another platform should be easy is not critique.
For actual critique, I think it is important to recognise that unsolicited critique carries the burden of needing to be delivered in a way that the intended recipient can be receptive to, otherwise it's just noise and is a bit rude.
