Twitter is not the government? Twitter also is not really a public square, it's an advertiser-supported electronic press.

If I own a printing press, I have the freedom to print what I want, including what people send me, and I also can not print what I want, including what people send me. It's my press. Want different rules, get your own or use someone elses.

Because Twitter is a privately owned super-fast electronic press, administered at their whims, people should stop using it for things that matter unless they have an actual contract with the corporation. I don't rely on Twitter for anything other than entertainment.

The fact that people expect rights and meaning with advertiser-supported stuff given to them for free is what's harmful.
