@dalias @marcan @theartlav One argument in favor of curl|bash: all realistic alternatives - third-party rpm/deb/etc., pip install, building from source, etc. - are just as capable of running arbitrary code but they _look_ less dangerous. curl|bash is honest about its risk and makes people think whether they trust the source.
If a project can use a sandboxed app store or run on a web page, that's meaningfully better, but almost no project considering curl|bash can do that.
