The fact that Trello got a lot of users by promising it would always remain free, for example? If I'd been a user I'd be rather upset about this sell-out. Fog Creek made it look like some nice side-project that others too could benefit from without ever worrying about having to pay for the basic version at any point. Sure they didn't owe anyone anything, but for me it confirms once again that no company can be trusted on their promises, ever. Now, of course we don't know yet whether the free basic tier is going to change, but we do know that (unless it's in the agreement) Fog Creek gave up control over their promise, which is prerequisite to keep it. Furthermore, I have the experience that few products survive an acquisition to keep the simple, successful formula they used to have. Edit: fixed unintended mistake in the company name
