I think it's a bit more than enjoyment. People felt a sense of ownership in the communities they helped build. And whilst they were always contributing to Reddit inc they still felt some control. Now that Spez has gone full on world's dumbest capitalist and keeps yelling about companies having to pay for "his" data, data which he didn't pay for himself, it's really exposed what's always been true. That Reddit is just another company, it's not your friend, it's not a community.
