> While I use Homebrew on my Mac — it is a major risk. I am afraid that the project is not following strict security policies and will be compromised at some point. Evil package or evil version of brew can steal or modify my data.

This is a genuine question: what is your threat model, and what security policies would you like to see? It's hard to imagine a threat model that assumes an "evil version of brew" that doesn't also prevent you from installing any third-party software on your machine. Malicious packages are always possible, but Homebrew's integrity checks do an adequate (but improvable!) job of making such attacks auditable; I'm not aware of any successful supply-chain attacks mounted against Homebrew users.

I have a lot of experience with various package managers, and Homebrew is not particularly out of band with its peers (which should be read, partially, as a general indictment of packaging practices).
