Sadly, all we can do is hope, they have little reason to open the source code if they themselves believe they are capable of doing it on their own, its a tall request to simply ask to "Take over" the development of the program.

I understand that this is kind of a hard request but I'm not asking to take over and become the leader of the code. They can still have the first and last voice in the project. Open sourcing just means people know how the system works, enabling them to perhaps script missing cards, or fix bugs, and for more ambitious people, add new features.

With that, a user could pull the existing source code, improve upon that code, and then request a merge, then the team would just need to peruse that change and merge it. This would allow quick patches to fix stuff and card scripting to be done by others then just regulated by the team, reducing developing time and increasing updates. That's basically the major advantage of open source programs and how all YGOPRO variants work, a team leading the development, but a community detecting and fixing bugs, improving the overall software.

we need more like you cause everyone on this project couldn't give the slightest fucks about the game or their community no update no explanation just plain out ignoring

I bet there are out there, we just need the code to start. I mean people will see that there is a chance to improve BFA and they will jump at the opportunity.

If they had separate teams working on both programs, they'd update on their own schedule, rather than around the Cardfight Area Schedule

Technically, they don't even need a team on BFA if they don't want to develop it. Just open source the code, let the community develop it, then when there is an update, just modify your code in the BFA server and that's it. It would represent literally a no work, all rewards situation for them and it would represent a better game for the community. Win-win overall
