It may be an anecdote when you read it, but as I personally experienced it I can assure you it was fact. Just brushing it away as an anecdote doesn't change the fact that it happened to me, I know it's happened to other people, and it will happen again. Enough anecdotes that all agree with one another eventually becomes an observation that should be acknowledged. Your "omg why are people claiming lag" attitude doesn't help at all in the face of that. Even if only 5% of the community is affected it doesn't change that this happens, and it's not just players whining because they screwed up. Acting all surprising and trying to claim that people should just know the rotations won't change the fact that you're obviously making assumptions that it's just people screwing up. Acknowledging people have technical issues means nothing when you specifically say
You can't acknowledge that some people have problems but in the same breadth act like it shouldn't be an issue at all. Packet loss makes your entire point null and void anyway.
The main point I want to make comes down to this. Some people do have network and computer problems. When you have the attitude that it should be easy just knowing the rotations then you have an attitude based entirely on false assumptions based on nothing more than your own personal experiences (see your own link for anecdotes), and we all know what happens when you make assumptions. I have no doubt some people use lag as an excuse, but assuming that they all are is an outright fallacy.
