As someone who didn't have much prejudice about the current Israel/Palestine situation, I appreciated seeing both sides; it allowed me to come to the conclusion that both sides fall short of my own moral values and therefore I don't need to involve myself in debates about the lesser or two evils.
Maybe other people with different morals than myself felt that one side met their 'good guy' threshold and wants to support them. They're free to voice their support, but I'd like to keep my taxpayer money in my own country where it can support people whose morals more closely align with my own.
Of course not, precisely because public speech including on media such as twitter is heavily censored.
The trick is gross but effective: treat ideas threatening to the system as illegal so they can be fought using the legal system instead of the political one. It's a power grab to silence Europeans. Same old trick used in China, Iran, any autocracy really.
The companies do that? In which alternate world do you live?
