Brimelow's blog has a disclaimer stating the opinions expressed there are his own and not those of Adobe. The WHOIS Internet domain name information service backs this claim, listing Brimelow, not Adobe, as the owner of Flashblog.com.
Adobe, evidently, was at least aware of the blog post just as it went live. The second paragraph mentions that a line was edited out on behalf of Adobe. The earlier version of the post apparently stated that "What is clear is that Apple has timed this purposely to hurt sales of CS5."
Brimelow's blog post closes with a final jab: "Comments disabled as I'm not interested in hearing from the Cupertino Comment SPAM bots."
Adobe has confirmed that Brimelow works for Adobe.
