In this case there is no grift (he is likely investing in AI like literally everybody else) and these comments are nothing but noise.
"Social norms" are a poor excuse for "ostracizing" someone who isn't even here to be impacted by it, let alone the knock-on affect of getting in the way of effective communication and discussion.
I wouldn't say that anyone's ostracizing him at all (It is on the front page...), and even if they are, putting it down to "social norms" is a bit disingenuous, don't you think?
We're not talking about Socrates speaking rudely about the people in power, we're talking about a billionaire accused (seemingly [rightfully](https://www.blockdata.tech/blog/general/where-andreessen-hor...)?) investing in bad-faith to scam people out of their money. I think that's a form of a theft, and calling an aversion to theft a "social norm" is technically correct but practically a massive misapplication of the term.
Yes yes, HN doesn't like a16z. Not one of those comments were useful.
