Why?

Is it the best out there? No. But it does work, and it provides me with updates for my tools.

Random curl scripts don't auto-update.

Me downloading executables and dropping them in /bin, /sbin, /usr/bin or wherever I'm supposed to drop them [0] also isn't secure.

Also, I find it is usually better to follow up with something like:

'It's better to use Y instead of X BECAUSE of reasons O, P, Q, R & S' vs making a blanket statement like 'Don't use X, use this other insecure solution instead', as that way I get to learn something too.
