See, the thing about this comic is using profanity as a way to demonstrate non-conformance. But this does not seem to be the case here. Nobody here thinks that Zach is going to lose his job due to language.

What I see is the opposite, actually. I started watching Zach's video on the Play app, in which he drops a "play some fucking music" in there. I couldn't help but think "Aww, he thinks it's cute to talk like a brogrammer".

Put that together with the slide in his talk, and I can't stop having the impression that his use of language is more of an attempt to "sound cool" to his peers than to he actually "being himself".

It's the same as teenagers smoking due to peer-pressure.
