wouldn't that original purpose be considered a "voting ring" and therefore abusive behavior ?

I think "End of Public Support" would be a great replacement

@SergiyKolodyazhnyy yes! Your answer says basically the same, but is much better worded.

@SergiyKolodyazhnyy, thats what I mean. I think we shoudln't generalise and say we should update answers with edits, if they are outdated. I think we should be very careful with editing and therefore changing answers, especially high/or accepted answers. At best this should be evaluated at a case by case basis. But comments are better for this, In my opinion.

@Tim, that would mean updating every answer that references any out-dated information - like previous java versions, ubuntu versions, etc

That's why I'd suggest a comment or an answer, depending if there already is an accepted / high rep answer. Regarding questions: we currently have a tag "software-center" with about 13k questions. Some of them are genereic (about repos or updates in general), some are specific about software center. So editing answers in bulk would definitely not be a good solution, I think.

I think a comment on an accepted and/or high rep answer or an additional answer is more in line with how things are done on askubuntu.

Yes, questions why this PPA isn't working are legit, as are questions regarding dead links to Ubuntu Software Center. But in my opinion, that doesn't mean we should edit all answers and replace the links. I mean, with your logic.. what would happen to questions regarding software center ?

That green icon in the notification bar can be so satisfying!

It's worth pointing out that this won't reject the original edit and the user will still get +2 Rep (if < 2000)
