Echoing the other comments, this is a pretty naive understanding of how a general purpose smart contract blockchain works and the incentive models involved that keep the kind of censorship described here from happening. They also don't seem to fully grasp how smart contracts that are in-fact decentralized work, and are cherry-picking the ones that have an authoritarian controller because of the nascency of the technology.
The article isn't really detailed at all, so it's hard to know where to start with why these "services" aren't in fact "centralized."
It's effectively the equivalent of someone saying "you can't keep your password secure from hackers if you store it in a database, if someone hacks it then they can steal it and use every site you used that password on": it's just obviously false to people who know how this works, but now I have to explain how hashing works and such.
I'd just encourage reading up on how Ethereum transaction mining works before just taking the article's claims at face value.
