This is on the level of "does that hurt? Then don't do that" advice from doctors. Yes, it's correct, but in the context of the discussion it misses the point. This is a post about Shadowrun and it's mechanics, so I am voicing my opinion on Shadowrun's mechanics. I know I can just not play with Shadowrun rules. I don't play with Shadowrun rules daily. But if that was a valid response to my opinion there wouldn't be any reason to discuss the rules of Shadowrun ever. You either like it or you play something else.
And yes, "like it or play something else" is a valid response to an opinion, but for people out there who haven't played Shadowrun, it's still worth voicing why something is disliked so that they can form their opinion without having to drop time and effort getting a session together just to give the rules a test-drive.
So coming to a discussion about the quality of the rules of a system and the opinions people have on said rules and saying "well just don't use the rules then" is dismissive and pointless. It almost reads as shutting down the opinions of others, even.
