I think it is because jews were already in full power. Freedom is an illusion that is good to uphold, because it reduces resistance to your power.

So prior to social media, the jews controlled every election through MSM, television, music etc. This allowed them to lul everyone to sleep by singing about everyone having freedom of speech etc. To jews, as long as you don't have freedom of reach, they don't care. If you yell into the sky, they're fine with your speech because it doesn't hurt their power.

Now, with the rise in popularity of social media, they wanted to elect Hillary Clinton and everything worked according to plan. The only problem was that social media influenced everyone to elect Trump, kek magic.
For the first time in decades, they lost control of their democracy.

THIS is why they started censoring. Prior to that, your freedoms didn't stop or hurt their power in any way, so they allowed you to have them. Now, they have to be increasingly abusive with their power in order to keep it, because no one likes the jews.
