>It's like how "jaywalking/jay walking" was popularized - the term itself was pretty crass for the time, the word "jay" conjuring thoughts of some kind of drooling, unintelligent yokel. Back when car infrastructure was still in its infancy, how would you argue that cars shouldn't dominate all streets and cities when the government- and industry-approved name for your action was literally "stupid walking"?
That makes sense because as you said, "the word "jay" conjuring thoughts of some kind of drooling, unintelligent yokel". The same can't be said for "side", aside from vague accusations that it's not "official" therefore normies think it's bad, but I can't see how you can get away from that accusation without using meaningless phrases like "type 2 install" or whatever (though I'm certain that would get similar amounts of ire for being "second class citizens" or whatever).
Well, yeah, it's not nearly as extreme, companies have become much better at PR. Still, the insinuations of something being unofficial, unrecognized, unsecured, really half-unintended still paint a picture of how Google wants its software to be seen. Like, I have no doubts that if Microsoft decided to start locking down Windows PCs to the Microsoft Store (the "intended experience" that they probably already imagine for their model customers), the temporary bypass will be accompanied with a prompt like "DANGEROUS: Are you sure you want to enable Unsecured Mode? (Y/N)"
