It gave them the excuse to build their own platforms in which their ideas could spread uncontested and at the same time made them more alluring to the masses because “forbidden” knowledge is so alluring to humans that perhaps the most famous myth in history is about how our species lost the perfect existence because of it.

You cannot make anything forbidden and expect that by doing so it won’t spread because it is forbidden. As long as there is a demand for it it will continue to spread and if the Streisand effect holds it will spread exponentially. This applies to ideas, drugs, guns, and pretty much everything. If the people want it they will get it. Alcohol is the perfect example: we tried to make it illegal and all it did was increase crime, violence and people kept drinking as much if not more than before. Fast forward to today people drink less than ever because they have learned the health effects of it. Give people the tools to tell right from wrong, correct from incorrect instead of trying to bubble wrap their world and then act surprised when they feel betrayed because someone told them there is another point of view (false as it may be). Let them see both point of views and let the very absurdity of the opposite view discredit itself.

If we cannot trust that people can make the correct decisions why then would we insist on democracy?
