Id have to agree with you, if a big business put a lot money they can easily manipulate and censor you.
But there's another concepts of blockchain out there helping against censorship, like BitTube https://bit.tube/ is a peer-to-peer, decentralized, censorship-free video sharing and live streaming platform based on IPFS and blockchain technology, this IPFS allows even if a government blocks a domain, its still possible to access the data through a hash.
