I'm a big supporter of open source software. However, I pay for a copy of Aquamail. I also paid for a version of K9, in order to support the developer. Aquamail is a good product and the developer is continuously improving it. I would hate to live in a world where your only options for email would be to use one of the big providers (gmail, office 365, etc). BTW, Aquamail is free, just not open source. The free version has a few limitations, I think, like a non-changeable signature.
