Fogcreek stated that Trello will not go away and i guess its a pretty safe bet as they are making their money (and plenty of it) elsewhere. Of course you can pay for it to feel better about it, but i dont think the success of Trello impacts Fogcreek a whole lot.

Supporting a product that you use regularly feels good. Personally, I can afford to live without Evernote Premium as I don't upload much and don't use premium features as much. But still I'm a premium customer because they are doing a great job!

I am not saying that paying for it isnt a good thing. But it wont make much difference to the creator of Trello and wont impact the lifespan of Trello all that much. They can afford to shut it down whenever they want or to keep it running for as long as they want.

Not being disrespectful or rude, but a (big)group of people like these will surely make a difference.
