I'm not sure if this is helping anyone except making people who are not bullshitters more paranoid and the bullshitters be-hated. The bullshitters in the startup world don't get big because nobody realizes that they are talking a lot of bullshit but because those who collaborate with them are at least as greedy as they are. (I was also drinking the kool aid for some time.)

So the core problem is greed and not bullshit, and this is also what makes it toxic. FWIW even the most credible and knowledgeable people are able to fan out bullshit, everybody does this every now and then.
