The internet is not some grand parlor where distinguished gentlemen sip fancy teas.
It's a truck stop bathroom, and it's forums are a gloryhole where dicks go in and bad ideas come out.
What kind of fantasy world are you living in?
Owners want to keep the platform in their image and politicians want to make the Internet in their image as well. It's all about control. Some of it is warranted, others not so much.
The wise wolf who's pride is her wisdom isn't so sharp as drunk.
Nothing happened to the Internet, as it is for the most part only the amplified well of the people who use it. Something has happened to the people in question, but the Internet as a platform is largely still as it was - perhaps a bit more commercialized and monetized, but that is always the general arc of things.
"We're more of the love, blood, and rhetoric school. Well, we can do you blood and love without the rhetoric, and we can do you blood and rhetoric without the love, and we can do you all three concurrent or consecutive. But we can't give you love and rhetoric without the blood. Blood is compulsory. They're all blood, you see." ― Tom Stoppard, Rosencrantz and Guildenstern are Dead
The Internet didn't change.
People changed.
People who have access to the Internet, as time went by, changed.
Authoritarian tyrants will always try to take over any free space.
The price of freedom is eternal vigilance.
The Internet was a mistake.
Yes, the PC movement has been hugely detrimental, but to be fair the far right is just as bad with their religious flounderings. The difference is for some reason people smart enough to say it's not cool for someone elses religion to dictate how you live can't understand that it's not cool for someone elses feelings to dictate how you live either.
Before the internet we heavily relied on scholars, people who actually knew their shit not people with Google PhDs.
These ignorant people use the wrong, incredible sources that they find on google (basically shit that's on page 2 and on in the search engine).
These sources are Brietbart, Stormfront, etc. Rightwingers in general are much more paranoid and hostile so they are easier to manipulate. Liberals are easily swayed by facts that are interpreted in their favor.
I can't speak for all companies, but social media presence was never that big a factor for my company - it didn't come up when I was hired, and it hasn't been a factor for any of my co-workers hired during my career (currently 15 years with the same company). A basic background check will tell you a good deal more about a potential hire than stalking through their social media, the majority of which is an idyllic misrepresentation of someone's life in which highlights are openly shared and the dark stuff is generally disguised or simply goes unmentioned. About as useful as a CV or resume, really.
