> The company also managed to acquire full rights of the Redis trademark and project stewardship from antirez after hiring him
How did that happen? He must have given/sold it to them, right? I remember him making an announcement that he was done with Redis and stepping away from involvement.
The only public record I've seen him talking about it was in https://github.com/valkey-io/valkey/issues/544, where he mentioned having sold the copyright.
Impossible to know as an outsider. They could have tricked him with false promises ("we'll take good care of the project and always put the community first, trust us"). Or he could have decided that the check was big enough and not really cared beyond that.
