Serious question - can someone please explain the purpose/appeal of these "Why I Left X" blog posts/videos? I'm from a generation where you didn't publicize this kind of stuff, and I'm not quite sure I understand the intent/social value of such posts/videos outside of the "whistleblowing" types of posts. Absent of any context, these posts/videos just strike me as self promotion.
Because blogging and publishing videos is easier than ever. Nothing has changed about the culture. In 1972, if someone left a company, they would willingly tell anybody who cared to ask.

At least for my cohort, that's not the reason why you didn't do it. You didn't do it because it was career limiting. There was value placed on a person who had a sense of discretion.
I'm sure a lot of HR types Google their candidates. I'm wondering if any would drop a candidate for having posted these things.
