I honestly don't see how companies, that aren't monetising Cassandra, providing resources to the project is a major risk to Datastax. This only improves Cassandra's mindshare in (and share of) the market, while leaving them to corner the large corporate client base as well as target their engineering efforts on things that can directly yield revenue. Although I think you overestimate the inclination and ability of these corporations to invest - at least to date, only Apple has demonstrated any capacity or willingness to do so, and they are fairly slow about it. Their lawyers and antiquated deployments lead to very few (but quite big) improvements, and so far all of them have needed help from Datastax to be incorporated. This is despite a largeish team of people with direct experience of participating in the project; no other SV company has any such employee at present, and bootstrapping such a team would be non-trivial. Instaclustr claims they intend to do this, but it remains to be seen how successful they will be.
