There’s absolutely nothing wrong with this. Every enterprise OSS company operates like that. People paying for support and funding the project get to make requests. Anyone else can submit a PR or be happy with the free software. It’s a pretty good deal if you ask me.

Granted, Oracle charges a lot just to even use the software, but I still don’t think it’s unreasonable to limit certain types of requests for higher paying customers. Pay base price and you get to use the software, get updates and call tech support. Pay a premium and they prioritize bug fixes and features for you.

The "no guarantee of fitness for a purpose" people put on the terms of software they sell is bullshit. There is something wrong with selling software with some functionality and then requiring customers to buy other pieces of software to make that functionality work.

That said, yes, they still handle that bit better than most large companies.
