Anyone making this argument is saying they have no idea what they're talking about. Well, either that or you're intentionally using inflammatory rhetoric, which does nothing but contribute to the heated atmosphere. The dev team have been very clear that the PC and the XBox versions are one and the same codebase, there is no "porting" to speak of.
The problem is, for every reasonable person like you, there is another who is impatient, intolerant, and just looking for a fight. On both sides. The sim is not perfect, nor is it total garbage, and anyone holding one view or the other is an irrational extremist. There there seem to be not many of the former, and a lot of the latter, here at times.
Also, a lot of folks here obviously know next to nothing about software development at the scale of the sim but still seem to have lots of opinions on how it can/should be done and rather unreasonable expectations. That doesn't help, either.
But I guess that's just human nature.
