Repeating my comment from every time PyInstaller is being discussed:
One issue with PyInstaller is that, by default, it includes all dynamic libraries that the Python interpreter has on your machine. It makes sense, it needs an interpreter and collects what is needed for it to run.
Unfortunately this might include libreadline.so, which is licensed under GPL, making your resulting executable unable to be distributed under a proprietary license.
There are ways to solve this issue, but one has to search and read documentation (and code, in my case -- when I was researching it, the docs were not clear).
