The question in question: Should the weight of downvotes be increased?
I have read Why was this question about increasing downvote weight locked? which says it was probably locked due to an abusive edit, via a mechanism that no longer exists (a fixed bug with rollbacks).
The Q & A seems like a valid discussion still relevant to the network today, which people might like to vote on, at least. Maybe there is merit in being able to maintain the content as well. The lock prevents these things, for a reason that is neither visible nor relevant today.
A number of questions have been closed as a duplicate of Jeff's question. Ending up at a question from a co-founder of the network that is locked without obvious reason is a slightly odd experience.
A similar question Should we have a policy about "too much downvoting"? by the same author of roughly the same vintage is not locked.
This question isn't about what should happen to the Q & A aside from it potentially being unlocked.
