This is such horseshit. Computer Science gives you the intuition needed to guide you to making more correct decisions you make in building your software rather than wrong. When you have these practitioners hitting the scene all of a sudden who just simply learn xyz latest framework/tool/fad and then are faced with a new and interesting complex challenge (for example, computers all of a sudden now have multiple cores! surprise!), they do not have the background to adapt and spend much time cutting their teeth, creating many bugs in their wake.
If you think that having the theory makes you write worse software, I feel bad for you because your computer science education must have been shit and you probably wasted your money. In that sense I understand the bitterness that a lot of people have.
