Just because things are not as one wants, does not stop that desire to be there.

Potentially, potentially not. I used to release software under GPL and LGPL but changed my mind a few years after that. I did so in part because of conversations I had with others that convinced me that my values are closer aligned with permissive licenses.

So engaging in a friendly discourse with a maintainer to ask them to relicense is a perfectly fine thing to do and an issue has been with chardet for many, many years on the license.
