For the reasons I gave in that same paragraph.
I agree that you made more lucrative offers than Basecamp, but they presented their offers (publicly, at least) in a way that feels more professional and respectful of their employees.

I didn't say that poor communication is what qualifies someone as a tyrant.
You did say, as interpreted by the reader, that his poor communication skills makes him come across as a tyrant, and therefore that is what makes him a tyrant.
That may not be what you meant, but in that case we're right back to you and the poor communication skills of your own.
