It's a world wide web, not your local pub.
'Public' means public. Use the privacy options if you don't want something to be public, your tweets to go viral, or your photos recycled as memes. Or someone to train their terminators on your stuff.
I'm amazed that people broadcast their views and post their photos on social media and forums and then complain that folk hurl abuse at them. The internet is not your lounge or your local pub. It's a big world out there. A percentage of people will disagree with absolutely anything you say, and a percentage of them will be rude, aggressive, racist, misogynist and quite nasty. A small percentage of a very large number is a lot of people and a lot of negative comments/hate. I've had endless amounts of abuse over the years. At first it gets to you, but after a while you get used to it. It's a learning process. We are acclimatising to the internet. All new tech requires that. Print, radio, TV and now the net. The solution is not to pick those who have a bad experience out of the crowd, magnify it, and then exploit it, as governments do, as an excuse for censorship. 'Public' means public. Understand that. It's not a tech problem but a human nature problem.
Google are making a rod for their own backs with the arrogant, petty attitude of some senior staff. Having enough lawyers to squash and silence staff or competitors may be the American way of business, but it gives governments their point of leverage. Big tech does not appear to understand that governments have been taking down the competition for centuries and are rather good at it. These are people who can turn them off, regulate them out of existence, use them as a revenue stream via fines and taxes, or recycle them as an outsourced provider of a surveillance state infrastructure. Big tech's arrogant and unethical behaviour is a free gift to the people they should really fear.
