Put your money where your freedom is.
Big tech censorship not only mutilates modern discourse, but also drastically alters the historical record for future generations.
Open source is a force of nature, like gravity. Transparent systems will eventually take over the global infrastructure because they have been ruthlessly peer reviewed and evolved.
Tech companies that don't talk about freedom are not your friend. If they could they probably would, but they can't because they are locked-in to surveillance and censorship business models.
