It's usually a good deal to buy out an investor that isn't on board with your current direction. Otherwise, they'll be a nuisance going forward. Better to make room on your cap table for new investors that are on board and will want to put in money in later rounds.

And remember not to take money from this guy next time. Fickle investors suck.
