You don't have to change it just because one person complained. I personally like the "copy and paste curl command" to install something and I'm sure many others do as well. It's very convenient, and I can inspect the file myself if I'm that paranoid about it.
Sorry, it wasn't meant to come across as a complaint with copy and paste curl command, I agree with you it's convenient and I generally like it.
However, the sort of tools that generally provide it also generally have a GitHub link nearby to encourage reading/writing the source. That too is convenient and I generally like it. Seemed like a fair suggestion.
