Allow editing archived threads

“Commenting is no longer allowed on this thread.”
Can’t you please make an update allowing users to edit their threads, I see no point of locking threads after 2 years of posting, editing is always needed, so can you please allow editing and even commenting on old threads?

I don’t think it makes sense to allow commenting on thread which is 2 years old. If you have anything to write on the same or similar subject, please just create a new thread.

And what if the thread was on top results on google search, do you think it’s easy to just delete it and create a new one? the new one may not be on google search anymore, also allowing editing and commenting isn’t harmful, is it?
