But the problem is that /usr/local/bin is in the default PATH. They defended this discussion to take over until Apple silicon came and they “silently” fixed it avoiding admitting anything wrong in the beginning
I don’t really understand what the problem you’re referring to is: /usr/local is explicitly the non-OS software hierarchy, which is why Homebrew used it. When Apple Silicon came out, the prefix was changed as part of allowing native and Rosetta-driven Homebrew installations to co-exist. There’s no nefarious reasoning behind it.
Edit: a thread with a bit of the history can be found here[1].
