This seems mostly reasonable, but also seems like it has some unstated (rare!) exceptions that maybe seem too obvious to state, but that I think would be good to state anyway.
E.g. if you already have reason to believe an organization isn’t engaging in good faith, or is inclined to take retribution, then giving them more time to plan that response doesn’t necessarily make sense.
Maybe some other less extreme examples along the same lines.
I wouldn’t be writing this comment if the language in the post hedged a bit more / left more room for exceptions, but reading a sentence like this makes me want to talk about exceptions:
When posting critical things publicly, however, unless it’s very time-sensitive we should be letting orgs review a draft first.
Makes sense.
