brew uninstall python@2 seems to have helped. Maybe.

Comment 2

Looks like this is a known issue with Homebrew Python and has something to do with an OpenSSL conflict?

Since the issue seems to be entirely localized to internal Homebrew stuff, and since there are workarounds/fixes (which you've already noticed), I'm closing this.
