In other words, a lot of time is spent attacking straw men that don't resemble what professional working designers actually do. The attitudes and beliefs attributed to designers sounds more like it comes from people who pass themselves off as designers because they have a pirated copy of Photoshop, so the only lesson here is that people who are clueless about design hire clueless designers.
We hire pro designers for everything, and while I don't love the 'B' logo Patrick chose, I can easily make a case that it is more professional than his current logo. I think your comment crosses way over the line into hyperbole.
I don't think it's hyperbole at all. That the 99 Designs "logo" is as terrible as it is, proves nothing about the almost-as-terrible logo that is in use now.
How is it hyperbolic? Your definition of a "professionally-designed" logo excludes the normal professional process for identity design. Then you conclude that engineering always beats aesthetics.
