The name of a political movement matters. Always has, always will. It's no different for adjacent concepts that describe a phenomenon the movement is organizing against.
Like shit.
The word spread in common usage about as fast as wildfire because everyone immediately knew what he meant. And the companies are too polite to even be able to say the word! If you can't swear in response to being degraded, pissed on, pissed off, used and thrown away, then you're the kind of sheep they want that they can abuse more and more and more and more and more and more and more without ever facing any consequence.
God forbid that rudeness is involved in collecting the power to stand up to it
Giving something a derogatory name that the yellow press (or rather some Telegram group) can sling around to vent their frustration and fear could be a win in this place. Of course, leadership persons of such groups are usually just demagogues looking out for their personal gain, so it might just as well be another rallying cry leading to really bad policies hitting those that vote in favor the most. But such is the world today ;)
Is Australia not big enough to count?
Plenty of terms are used in senate hearing transcripts. Hearings are a completely different thing from actual laws being passed.
As I said, this is a fundamental misunderstanding of how the government operates.
Is that the argument? I understood your argument to mean that the term "enshittification" is holding back the movement because nobody will use it. As others are saying, I don't think there's any issue people take with some drop-in term being used if actual laws are passed discussing the topic.
Plenty of movements involving vulgar language, however, did result in laws being passed - "Fuck the Draft" comes to mind, the attitude surrounding which led to the draft ending (after all, why else would it end?), but also was a central fixture in a supreme court ruling that furthered defined 1st amendment rights in the USA.
So again, I just don't understand how one intellectual describing one aspect of the digital rights movement could negatively impact the movement as a whole, which I interpret as your argument.
