Well, it's a difference if they only use blockchain as a technology or they also incorporated cryptocurrencies into their business. This is not the same thing but people often mix that. Using blockchain doesn't necessary be connected with using crypto.
Anyway, both blockchain and use of cryptocurrencies in businesses is a good promotion and helps to raise awarness of people about these technologies and possibilities of their usage in different industries but doesn't necessary increase the adoption.
It doesn't matter how they want to swing it. If they were truly "entering" into crypto, they'd be learning to use Bitcoin, they'd be advocating for it. Accepting it. Paying staff salaries in Bitcoin. Promoting open source. Getting people to actually devote some resources to improving and developing it.
So yeah, doesn't matter if they're all developing their own crypto or blockchain. They're in it for the money. Nothing wrong with that either. Just no need to pretend otherwise.
