These two changes do not look good to me. Having no quote button for locked topic was good, we would not need to waste the time to write a response then discover the topic is locked. Also the factoids were good too.
I think it is a good change, it makes it easier to quote posts from locked threads. also, it is usually noticeable when a thread is locked since the lock icon is right next to the title of the thread so I think there won't be a lot of people wasting their time writing a reply since it is noticeable when a thread is locked.
