 You should only ever sudo a tool you trust. Of course, you can trust Homebrew 😉 — but do you trust the multi-megabyte Makefile that Homebrew runs? Developers often understand C++ far better than they understand `make` syntax. It’s too high a risk to sudo such stuff. It could modify (or upload) any files on your system. And indeed, we’ve seen some build scripts try to modify `/usr` even when the prefix was specified as something else entirely.
 
 We use the macOS sandbox to stop this but this doesn't work when run as the `root` user (which also has read and write access to almost everything on the system).

 Homebrew installs software from across the open source ecosystem.
 That makes the security of the software supply chain, the humans involved, repositories, build systems and download servers that turn source code into something you run, a core concern for us.
