I think your definitions don’t quite match common use. When people think about sideloading, they think about installing apps from a third-party source that are not approved by the primary vendor. That’s precisely what Google is going to block.
See the end of my pervious comment. The fact that we call that “sideloading” in common parlance is a magic trick Google has already played on us and we ate it up. Resist.
The way I understand sideloading is installing an app through a way that isn’t Play. So F-droid - as one example - is sideloading because you need to go through the overly dramatic warning messages to enable the install from unknown sources. If all the devs in F-droid’s repository theoretically registered with Google, nothing will change. The only difference is that Google wants to know who made it. They make it harder and shittier and thus limit our choices, yes. But they don’t block everything outright.
The problem arises for apps, whose developer doesn’t want Google and by legal extension the American judiciary to have access to their information. That’s a privacy concern that I find very concerning too. I’m not defending Google’s choices here. I hate it. I also don’t like the inevitable hyperbole going the other way.
I think it’s the wrong label, anti-intellectualusm. Sense of reality might do it more justice. I think there are two factors at play. 1) how much does higher education cost you? Does it put you in debt you’ll be lucky to have paid off before you retire? Have other people gotten degrees and still ended up unemployed? Why get majorly in debt to get no job in the end? That’s more a North American specific problem. I’m in Asia and I haven’t heard anybody shit talking college degrees in favor of the trades. 2) We need plumbers and carpenters and welders and whatnot. And due to declining birth rates in many places and the fact that the numerous birth years of the boomers are retiring and will continue to retire in the short term, we are running out of sparkies, masons, and HVACs. So if you had to career advise people today, you’d be silly not to bring up a profession with near certainty of getting a job once you’re trained up.
Shitty work environments exist in more high brow professions as well.
