Let me first say that I respect you and RethinkDB immensely.
Rather than comment on toxicity, I'll state a fact: in the company I work for, which makes heavy use of open source software, is relatively sophisticated, and is legally cautious and conservative, AGPL software is verboten. It's a non-starter. Do not pass go. Do not collect $200.
So, in the absence of a company that can actually offer a valid license to the product, there's no chance of considering it, let alone using it. This may seem overly cautious and FUD inducing, but it is how things work in our litigious world.
