> What Why can't I find a USB-C hub with multiple USB-C ports? was looking for did not exist at all previously (except for one Dell hub). Yet, people posted many answers because USB C is confusing or they just wanted to be helpful and of course they totally failed because they answered a totally different question. Moderation also failed because these answers were not removed but I digress.

You are right.  The community moderators and the moderator team failed.  We failed to identify what commonly is referred as a “rollback war” and we should have identified it a year ago.  The question and answer should have been protected in 2020 to avoid what has happened since.

> Which is exactly what the question is looking for. This capability makes all answers, which boils down to "no such things but here's something else" anyways, completely obsolete. The answer is now: get a TB4 hub.

Only the author of the question gets to decide what the accepted answer is.  I would argue that the changes to the accepted answer should have never happened in the first place since they significantly changed the answer.

A Thunderbolt 4 hub isn’t what the author of the question was looking for, it didn’t even exist, when the question was asked.

> Since it's so chaotic I have not posted this there yet because I do not know how, do I edit the existing TB4 answer which does not have this backwards compatibility information? Do I post yet another answer?

You already have an answer.  You should leave the accepted answer alone.  Your edits have been reverted by the author of the question every single time except the last one.  You are free to edit your own answer.

> I tried to edit the top answer https://superuser.com/posts/1414046/revisions and it was rolled back. Very frustrating!

Your edits were reverted by the author of the answer.  You should have edited your own answer instead of changing the words of the author or adding your own words to the answer.  If you did not have the edit permissions you have, I and a lot of reviewers, wouldn’t have approved your edits.

If you continue to edit that answer out of a mistaken belief you are right, it will catch the eyes of a moderator, you should instead focus on your own answer.  The next step to preventing changes to the answer is probably protecting it. **That shouldn’t have to be the solution.**
