The same goes for the freedom of speech. Europeans should make it legal guarantee instead of trying to build walls around speech. So when X or 4Chan etc deletes a post, it may lead to freedom of speech fines if deletion wasn't justified. Tha same for the algorithm, if a post that doesn't break the rules is discriminated by the algorithm, a hefty fine should apply.
Suddenly we will have companies that keep their business clean and no claim for moral high ground.
