I'm not sure what the alternative is or what you are advocating. Antirez stopped working on Redis 4 years ago. We were lucky someone created Redis "for the love of the game". Now before you there are a couple options
1. Antirez2 pops up and works on Redis because they love working on Redis
2. Someone is incentivized, with money, to work on Redis.
(1) didn't happen, so we must go with (2), and with (2) comes the problem of the actual business model that will be used to sustain (2).
A. Donations/Support contracts
B. Open "Core" aka I'm the only one allowed to sell this as SaaS.
Method (A) has shown to be an abject failure while AWS takes your revenue. Companies have successfully chosen method (B). Either you have a method (C) in mind, or you just aren't being reasonable in asking people to work on OSS for free. You can be mad about the "rugpull", but between the choice of "rugpull" and abandon the project, I don't see how "rugpull" is the worse option
