I don't think talking to anyone will help based on what you wrote. It doesn't sound like there's anything meaningful going on there unless they're somehow sidelining you and someone else is doing the work, in which case yeah escalating to the right people can be explored. I of course cannot comment on the legality of anything but you have a few options you can evaluate - be the initiator and implementer of work - maintain a separate branch and implement features/improvements there whatever you see fit and hope that some day you can pitch those and get it in the official product. Second option is to see if contributing to Open Source is permitted - if it is you can find some projects to help in your free time and in parallel keep looking for a better more meaningful job. This will keep you busy and it will help you with the job hunt as well. The third option is to just keep looking for a better job - invest most of your time and resources to that end. I know it feels very wrong to be paid to do nothing but ultimately you have to consider what you can control and what you cannot and do what's right for yourself.
