There are many open platforms. (I've contributed to those as well). Some are built on open standards. None of said open platforms have procedures or resources for handling the onslaught of disrespectful trash that the people we've raised eventually use these platforms for communicating at other people who have feelings and understand the Golden Rule.
The initial early adopters (who have other better things to do) are fine: helpful, caring, critical, respectful; healthy. And then everyone else comes surging in with hate, disrespect, and vitriol; unhealthy. They don't even realize that being hateful and disrespectful is making them more depressed. They think that complaining and talking smack to people is changing the world. And then they turn off the phone or log out of the computer, and carry on with their lives.
No-one taught them to be the positive, helpful energy they want to attract from the world. No-one properly conditioned them to either respectfully disagree according to the data or sit down and listen. No-one explained to them that a well-founded argument doesn't fit in 140 or 280 characters, but a link and a headline do. No-one explained to them that what they write on the internet lasts forever and will be found by their future interviewers, investors, jurors, and voters. No-one taught them that being respectful and helpful in service of other people - of the group's success, of peaceful coexistence - is the way to get ahead AND be happy. "No-one told me that."
Shareholders of public corporations want to see growth in meaningless numbers, foreign authoritarian governments see free expression as a threat to their ever-so-fragile self-perceptions, political groups seek to frame and smear and malign and discredit (because they are so in need of group acceptance; because money still isn't making them happy), and there are children with too much free time reading all of these.
No-one is holding these people accountable: we need transparency and accountability. We need to focus on more important goals and feel good about helping; about volunteering our time to help others be happier.
Instead, now that these haters and scam artists have all self-identified, we must spend our time conditioning their communications until they learn to respectfully disagree on facts and data or go somewhere else. "That's how you feel? Great. How does that make your victim feel?" is the confrontation that some people are seeking from companies that set out to serve free speech and provide a forum for citizens to share the actual news.
Who's going to pay for that? Can they sue for their costs and losses? Advertisers do not want a spot next to hateful and disrespectful.
"How dare you speak of censorship in such veiled terms!?" Really? They're talking about taking down phrases like "kill" and "should die"; not phrases like "I disagree because:"
So, now, because there are so many hateful economically disadvantaged people in the world with nothing better to do and no idea how to run a business or keep a job with benefits, these companies need to staff 24 hour a day censors to take down the hate and terror and gang recruiting within one hour. What a distorted mirror of our divisively fractured wealth inequality, indeed.
"Ban gangs ASAP, please: they'll just go away"
How much does it cost to pay prison labor to redundantly respond to this trash? Are those the skills they need to choose a different career with benefits and savings that meet or exceed inflation when they get out?
What is the procedure for referring threats of violence to justice in your jurisdiction? Are there wealthy individuals in your community who would love to contribute resources to this effort? Maybe they have some region-specific pointers for helping the have-nots out here trolling like it's going to get them somewhere they want to be in life?
Let me share a little story with you:
A person walks into a bar/restaurant, flicks off the bartender/waiter, orders 5 glasses of free water, starts plastering ads to the walls and other peoples' tables, starts making threats to groups of people cordially conversing, and walks out.
