What ever happened to the idea that people can express their own opinions without representing their employer? It used to be that many personal blogs had a readily visible disclaimer along these lines: "Opinions expressed do not express the views of my employer."

It was never much of a thing. If your social media posts cause a financial or reputational risk to your employer, they'll take action to resolve that risk regardless of a disclaimer in your bio.

See, this is something I highly doubt. Do you think that there is such a large part of Disney public that does give a damn about what Gina Carano says? I don't think so. I want to count the ones who actually stop watching "the Mandalorian" because of Gina Carano's tweets. My bet is that they're so few they'd feel stupid after two weeks and start watching it again.

I think the issue here is that taken one by one, each of those who have the power to take decisions succumb to peer pressure and fear of being targeted next. Everyone is replaceable, so everyone prefers to keep on the safe side when confronted by people who are aggressive, determined, and always ready to escalate the pressure to the the next hierarchy level or to to start working out the weakest peers.

So the bottom line is that if the targets of these attacks just stood their ground united and told the mobs to fuck off, the cancellers would just vaporise in a couple of weeks.

Yes, you are correct. Noting that [not] all cancel efforts are the same, and I'm sure there are edge cases and exceptions, it seems that generally cancel culture efforts often gain momentum when the target shows 'perceived weakness' and often lose momentum when the target makes it very clear they don't care. In the case of corporations like Disney, the very idea of telling people to "fuck off" as you say is anathema to PR culture.
