And even that was only possible because ruby central had been acting as a steward for these open source projects that these maintainers had built under one enterprise github account.

Ruby central does not actually own bundler or the other projects they locked down, the community at large does. They just control the github, and opted to bend to right wing pressure from Shopify and DHH and likely illegally took control of them.

They have backpedalled and said they will allow access back to the people that built and maintained these tools for a decade once they sign various agreements, but most have already fully quit or have stated they will not sign any agreement that comes handed down from Shopify/facists like DHH. On the plus side, some of them have been working on an alternative to rubygems, so there may be a community driven option for gems again soon.

As someone who dislikes Python, I can't say I agree. So, I will use Python, but I only use it for 3 lines of code snips to test before making codes on other languages.

They certainly tried (see Poetry, Pyenv, Conda, etc.). But that was mostly done by Python developers in Python, which is frankly the entire problem.
