These companies are backed into a corner. Even if they "realize" that they are doomed the investors won't allow them to just shut down.
"NewThing from the developers of Redis" holds so much more weight than "Redis is now closed source and you have to pay for it"
I disagree with this part. The problem we're now seeing with open core is that almost everybody just wants the core. They don't want enterprise. They don't want the new thing.
In this case, it's "Valkey, from the developers of Redis", and everybody wants the new thing. Because the people working on Valkey are in fact the people who worked on Redis before it went proprietary.
