Allow Uncle Holden to drop some wisdom of the ancients upon your tight little shota ass
Not one goddamn thing has changed.
What you complain of is not new. Its not even recent. Its not even from this fucking century.
Back in the early to late 2000s companies and politicians and media were terrified of being declared "unpatriotic" in the wake of the middle east wars and 9/11. People renamed fucking french fries to "freedom fries" because France didnt sign up for one of a half dozen brushfire conflicts at the time. Anyone who questioned this narrative without being rich enough or famous enough to get away with it? They suffered the same shit that those who piss off SJWs suffer today.
Then in the 90s you had political correctness's first incarnation and all the mediocre hypocrisy and prudishness we see today, coupled with the same faux-progressive narrative from businesses, media, and politicians. Same shit, different decade.
And in the 80s the satanic panic and moral guardians made their biggest resurgence since the goddamn 50s all over the damn west, and the same companies and same media you complain of being so egregiously bad and callow today rolled over and pandered to the screeching fanatics just the same as ever.
Political narratives being pushed on society, with corporations and media desperately clinging to them in order to stay nice with the powers that be, is shit thats been going on since the fucking roman era. And in some form or another probably beforehand. Hell some of my earliest memories of reading into history was of roman corporations bending to the more powerful factions in the senate, media of the time going out of its way to attack the senate's enemies both past and present (this kind of thing is why Caligula is known as such a depraved monster, since he pissed off the senate enough to have them go out of their way to destroy his memory afterwards), and popular scapegoats being singled out and blamed for everything (i.e. christians).
As long as there are people in power with different interests looking to advance their own power and influence, and as long as there are moral crusades and political causes and religious fervour to be manipulated and pandered to by these people in power, and as long as there exist corporate entities that are desperate to keep their name "good" no matter how much they must kowtow to idiots, there will exist the same shit you complain about.
Assuming that "oh in the past it was so much better and freer and more open" is vanity. There was never a "golden age" of intellectual freedom and openness. Just that these days this shit has become all the more noticeable because instead of the drooling fanatics and cynical profiteers spewing their bugfuck insane and idiotic rhetoric and reasoning in private and closed spaces which never got reported on by media and political figures who went out of their way to put a "sane and nice face" on their horseshit, they either do everything online for the world to see, or their private and closed spaces get recorded and spread to the internet for all to view.
So no. We did not "go so wrong". We have merely been given windows into the narrative process that has been fucking up human society for literally thousands of years. And thus we finally are able to start to counter it in real time rather than years or even decades after the fact
