Blockchain implementations in centralized black boxes are more likely than not the future of blockchain. As soon as regulation gets rolled out usable blockchains will be controlled by governments and/or private companies that comply with the rules. Not that I'm not in favor of a truely decentralized solution but I doubt "they" will allow this to happen.
Well they never managed to shutdown torrent or tor, so decentralized is still alive and kicking.
But yeah, we are likely to see a lot of people using the "blockchain" label for marketing reason, not using the tech for any of it's benefits.
But that's silly even from a technical point of view: if you don't need decentralization and transparency, then a blockchain is a very poor alternative to a blackbox built on postgress.
