This is OK... until you take the time to ask:

Why would they be helping "companies that ostensibly look competitive with Coinbase" just because they care about the ecosystem?

I'm not 100% sure on this, of course, but maybe they're not just doing this so that they can have competition.

P.S. Yeah, maybe they can buy / 'take ideas form' those other companies; that is, I think, the most probable scenario
