>I will never use Homebrew again because I'm still sore that they dropped support for a Mac OS version that I was still using and couldn't upgrade because Apple didn't support my hardware anymore.

How old was it? With macOS "running an old version" is not really a viable or advisable path beyond a certain point. Might be something people want to do, might it a great option to have, but it's not very workable nor supported by Apple and the general ecosystem.

>Any decent project should have a way to install without Homebrew. It's really not necessary.

We don't install homebrew because it's necessary, but because it's convenient. No way in hell I'm gonna install 50+ programs I use one by one using the projects' own installers.

Besides, if "Homebrew dropped support" is an incovenience, "manually look for dozens of individual installers or binaries, make sure dependencies work well together, build when needed, and update all that yourself again manually" is even more of an inconvenience. Not to mention many projects on their own drop support for macOS versions all the time, or offer no binaries or installers.
