Pretty easy when they took away my favorite app and tried to force me into their ad-riddled POS - along with their hostile treatment and shuttering of subs that didn’t conform. It was already getting to the point that, after a decade plus of being a “redditor”, the place was wearing thin. The constant reposts and karma whoring, the hive mind, the low-hanging fruit of quips getting the most upvotes vs a well-thought out reply, the shills and bots, they were killing Reddit IMO. The action against third party apps was the final straw.
