My hunch is that the two are not really related.

Companies of any appreciable size will be happy to pay for support if they choose to make Citus a part of their critical infrastructure. And the industry reached an inflection point where there are enough companies want as much of their infrastructure to be open source as possible, that you can run a company where most of your stuff is open source, while still making a ton of money (like RedHat, CoreOS, Docker, etc)

I know Red Hat is making a ton of money. But, CoreOS and Docker, are they at the "making a ton of money" stage, or merely well-funded by investors?

Good point. I wondered if I should edit that specific part, but kept it anyway.

But a sign of getting investors is also that they see that there's still potential of making a lot of money, in spite of being open source.

That's true here too. Citus mentioned they spoke to their board (and presumably their investors too) about this change.
