Output of brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Some installed formulae are deprecated or disabled.
You should find replacements for the following formulae:
  openssl@1.1
  youtube-dl

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  python-mutagen

Description of issue

Just a general question: who makes software available on HomeBrew? Is it the publisher? I'm curious in particular about the bitcoin formula. v26 has been out for a while but HomeBrew still only has v25.1 available.

The public. It can be the publisher, a user or someone else completely.
