Interesting, but:

In the startup, tech community, if you get fired, you become a persona non grata. That means all the social circles I had booted me out.

The article says this happened "many years ago." I can't imagine the part above applying any longer with the different ways in which people socialize in the tech industry even in just the last few years.

Even folks who've done pretty shady things, are potty mouthed psychopaths, or who have caused significant scandal aren't getting totally ejected from "the community" (partly because there isn't just one tech community, but still).
