The point of astroturfing (in comparison to the term it derives from, grassroots) is that it's not people coming together to support a policy, it's people with a vested interest in an entity taking cues from that entity to act in their interests in such a way that it appears as the former. The definition never shifted, the tactics just became less obvious. I would be less suspicious if more comments were complaining or giving measured thoughts, but they weren't.
I would agree that Waymo employees or shareholders shouldn't be commenting here without disclosing their affiliation. But that's a relatively small class: Googlers (and, increasingly tenuous, Xooglers) don't get paid by Waymo and don't get exposure to it through their GSUs. You can make the claim that Waymo's success adds to Google's brand prestige and has knock-on effects, and maybe that's true to some limited extent. But comparing that to being directly paid by the company to spread propaganda is quite the reach.
I didn't. I pointed out the less obvious ways a financial incentive might exist.
Excuse me for being skeptical of someone who uses a cutesy nickname for former Google employees.
You did no such thing, which is exactly the issue.
What's important is the existence or appearance of a conflict of interest, particularly if you're not disclosing your connection. Having a friend who works for Google who might be upset at criticism counts. Being a former employee with stock counts. Having any kind of monetary or professional interest in FSD companies succeeding counts.
If someone is presenting their statements as that of a person who is not involved, and they actually are, their behavior is duplicitous, and justifiably characterized as astroturfing.
