Hate to be "that guy", but you can probably make the FOSS alternative work for you. Create a feature/bug issue on the project(s) explaining the problem in detail. It might be easy to fix.

You can also try to fix it yourself, or ask a programmer friend to help. Friends often like helping friends.

For a smaller investment (eg. one month of ChatGPT Plus for Codex, Kimi, whatever) and you can probably fix all the niggly things that you don't like yourself. Just don't go opening pull requests for code changes you don't understand - it won't be appreciated.
