I’ll offer a counterpoint or two, and then, because I know this will just keep circling without end, I’ll bow out. 
You say a week would have been sufficient. I absolutely 100% guarantee you that the next person in line would complain because they wanted two weeks’ notice. 
And if it had been two, somebody would ask for a month, or “you can’t take them down, I need them to be available 24/7 in perpetuity.” Better to just rip off the Band-Aid* and be done with it, otherwise it’ll never get done.
And, regarding communication:
They communicate all the time. They’re incredibly open about any issues and about the reasons for a lot of the decisions that frankly they don’t have to explain.
I can’t think of another time when the literal owner of the company popped onto a message board to answer people’s questions and engage in a meaningful way.
Last thing: I’ve heard people complain that Privateer is bad at communication many times before. Usually I hear that charge levied when the recipient doesn’t like the way it was said or doesn’t like what they hear. These people demand full operational information at all times, instantly and at their whim, but get upset the moment something isn’t perfectly groomed in a press-release-style manner. Which…doesn’t make a lot of sense.
“A lack of communication” and “I don’t like the answer I was given” are two very different things.
* Yes, I literally mean the Band-Aid brand of adhesive bandages.
