> If I merely say "We will only maintain a business relationship if you stop saying X, Y, and Z," then turning down that business relationship is not a free-speech issue.

I think if there's any problem here it was with the way it was put. I don't think anyone would have had a problem if Chase had said, "We're terminating our relationship with you because of your blog's content," but the idea of them suggesting he change to maintain the relationship seems to have struck a chord. Perhaps it would have been better to leave that possibility implicit, but... The more I think about it, the more I think this blogger is drumming the issue up to generate traffic to make up for his loss of revenue.
