The net of what you should be cognizant of when providing insider information on a product from your company or commenting on a topic it is heavily involved in is wider than the single issue you eagerly dredge up.
E.g. the last thing you want from your comment about using <new product> early internally are news articles about "What Google plans on doing with <new product>" when you were just trying to give your personal opinion on where the technology might go.
To echo this comment, zamadatix is exactly right; I need someone quoting me about a Google project as an official representative about as much as I need another hole in my head.
As to the greater point, I want to emphasize that as a human being I want to be careful with how I communicate with others because I care about them not feeling judged, dismissed, othered, or otherwise insulted. The charge that the rules keep changing is overblown; it’s always about respecting people even if you don’t understand or enjoy them.
I know that some might still equate that with “cancel culture” but I can’t help that (and tbh that’s a discussion that we should have over beers and not on the internet).
