ForgeRock picked up a bunch of it and did just as objectionable things with the licensing - for all intents and purposes the the Sun identity stuff is dead unless you enjoy dealing with ghouls.
I’d say better alternatives to Auth0 today are things like KeyCloak.
Aah, yeah, I remember now, Sun did make a lot of stuff Open Source, but they used a slightly controversial license (the CDDL[1]) for a lot of it. As I recall, it caused a lot of grief for people who wanted to pick up their stuff and do anything downstream with it.
I do remember the name ForgeRock now, but I never used any of their stuff. By the time all that happened, I wasn't doing much in the IdM space anymore.
The whole episode is kind sad, really. Schwartz did some good things at Sun, and while their embrace of Open Source wasn't perfect, they released a lot of code and put a lot of weight behind F/OSS. If they had been able to continue as an independent company a bit longer, and not get borg'd by Oracle, it would have been interesting to see what might have happened.
I disagree. Oracle just continued the flawed open source strategy that Sun was already carrying out for many years. If Sun had continued, I think we wouldn't be much different than we are today. The OpenSolaris project was a great example. It was already dead way before Oracle bought Sun.
