Think about it: if you don't see, can't see, and have no record about what's run (because what's downloaded abd run isn't saved), you're just making your computer untrustworthy, especially if you're piping to a root shell. At least if you download the file before you run it, you can check the checksum / do a sanity check of the file before you run it, as others have mentioned. But nobody is saying or has ever said that it has anything at all to do with the download tool. Piping wget versus curl makes zero difference. Also, suggesting that installing via sh is a related issue is completely incorrect thinking. You might as well suggest that using a keyboard on your computer can be frowned upon since doing things on a keyboard could lead to compromise. The statement is true, but ridiculous and not helpful.
