Yes of course there is. Simply stating that a company like SS, who use to want all this honesty and transparency with their product and fans, are not likely to endorse a reviewer who gives less than an overall swimming nod to their product. Business logical; yes. Who wouldn't do that? However, consumer wise, the "fan review" becomes more of a commercial, and not an unfettered assessment of the item.
Again, no disrespect to Optibotimus, his review is cool and he's been stand up in here and probably a little too transparent with us, but I do appreciate the effort.
Opti, I do think, however, by NOT reviewing a truly bad piece shows that your actions can be swayed by the need to maintain your relationship with the manufacturer, so objectivity is, by its very nature, compromised. That's not a criticism, just an observation and again, no disrespect. Most, if not all of us, in your position, would do the same.
Hell, I like Sean's reviews. They are funny and annoying in an adult swim kinda way. They ought to give him a show on AS!
