Nobody controls open-source project.

Eh, people must learn - cryptocurrencies were created not for centralized development or product/service, but for a collective intelligence of people, who can/could make something better, with all people from the world make it even better.
Because of this you can fork any project you want and start your own network, with part of old community or with new community.

And now for what cryptos are used? Obviously Pump and dump, because it's unregulated market.
Obviously it wasn't a vision of early developers (or at least I hope it wasn't).
