It was inevitable. Not because of imgur going bad (did they? They did take some questionable moves regarding direct image links, but can't blame them considering volume). It's because of ye olde adage here on HN. If you your business relies on someone else, be prepared for their moves (to not use harsher words). Large volume of popular reddit-submitted content is imgur based. They have to get (back) that under control. Smarter move would be to outright buy or merge with imgur, considering their content and user base, but that probably have been considered.
