I believe you are one of those that always want to talk against regulation and decentralization. Ethereum is a typical example of what decentralization is all about so why now do you hate it so much? I think you need a deep study of how ethereum works then you can rethink about you calling it a scam
Yeah, he really needs deep understanding of how Ethereum works, every company have their vision and one of the vision of Ethereum is to create a decentralized system like that of bitcoin, and when you call a system a decentralized one, it will surely give opportunity to different kind of people without segregating, but with the proof of stake that are planning to develop, I believe that it will make the system stronger.
Ethereum cannot reject any project that comes for its smart contract, which is why they do advise anyone that is participating in those projects too to do their own due diligence before investing in any of them,Ethereum smart contract will always be open to everyone. The only think Ethereum can do later is for them to implement KYC, and maybe through that, they will be able to be strict with any project that intends to scam, but if that is the case too, it will still be more of lik operating a centralized system.
