If you think its weird that a for profit company is making money and no one is complaining, its because everyone went into the deal knowing exactly what's what. No one was tricked or deceived.

The deal never included that they would appropriating the community content and selling it as their own, but that could try to make money from user-generated content, and in turn they would keep it as open as possible: an easy to use API, third-party clients, RSS feeds for every subreddit and even posts and comments, etc.

They changed the deal. People are right to be upset with the new terms.
