Yes, it is. Then again you'd be shocked at how much companies pay for SAAS apps today. I like to think you use FOSS when you're small b/c you can't afford the good stuff, then you get so big you want to switch back to FOSS b/c so many companies are taking you for a ride.
Yes. But it is very easy to selfhost yourself (probably what you want in an enterprise setting).
I agree. I look forward to you releasing a feature-complete competitor at $2.49.
