Back in the "old days" you had, in my opinion, even worse issues with Media Metrix and Nielsen. They were the real gangsters - and it was really expensive. Comscore was the new kid on the block and tried harder to get good data out there. I don't recall any extortion from them.
When someone is running a business I think it's a good idea to focus on the business and not on various crusades. Whenever I see someone behaving like this I'm glad I'm not an investor with them. Watch what happens with Mahalo - all these shenanigans and the ceo's focus on angel investing tell me that the level of his interest in his startup isn't all that great.
Or he's magically talented and can do it all while building a great business.
