So people also use the term “news provider”? What about “email channel”? This argument falls apart fairly quickly with any level of scrutiny.
The English language has connotations. Certain words are more likely to be paired with others due to cultural or historical reasons. “Instance” has a medical and technical connotation; and Lemmy is a technology (software). News is not technical, so it is unlikely (but still correct) to use the word “instance” with it.
Email is more of a service than a technology, so due to connotation, it is often paired with “provider”. However, “email instance” is still a completely correct phrase.
Once again, we should not be calling fundamentals of the English language “gatekeeping”. This is how you get widespread ignorance and shitty communities.
P.S. Also, your “no one outside of Lemmy” argument is also just wrong. Invidious, Redlib, and other frontends refer to themselves as instances. Bluesky calls itself an instance. And it is very common to use the term for weather services as well.
You assume that educated people are making the final decision, when that has not been the case in at least 60 years.
Economists can scream from the roof-tops that the wealth-gap is harmful (they have), that ignoring science is regressive (they have), and that tariffs are fucking stupid (they have). But if the people in power (i.e CEO, Lobbyists, President) simply ignore them and do stupid shit anyway, it’s all pointless.
Moral of the story, this is not on the economists. This is on the stupid being in positions of power and the ignorant masses not holding them accountable.
