Yeah, the overall UX has needed updating for quite some time, but I also imagine their paying customers (photo nuts) are some of the pickier users out there. I wouldn't be surprised if the best course for Flickr is to be as conservative with changes as possible.

Even if it's the best course, it might still wreck on the coral reef cruft of dead accounts and abandoned groups. Flickr has been in decline for a while. I doubt incremental changes could bring it back.

dead accounts and abandoned groups don't pay for their accounts. those who do pay are the picky users.
