I get your sentiment, and while some may disagree (most of this is subjective, anyway), there will be many who agree with most of your points here. However:

> Now they're focusing on Exchange support when the best email servers on the planet have nothing to do with Microsoft?

People don't want Exchange because they like Exchange. For people who like Microsoft, the very last thing they care about is that their email client communicates with their server over Exchange.

This feature is for the unfortunate Linux fans, like you, who are stuck with a job that requires them to interact with a Microsoft server. That's not dumb, that's a smart move on the TB side (well, lucky, perhaps, that people are willing to work on it, more than being smart) to allow users to use TB in the first place. If you don't use Exchange you won't mind the support (barring perhaps reduced development elsewhere), but it will let many people use TB where they otherwise _could not_ without plugins.
