I don't see where it says that. Can you provide a direct quote?

Footnote 2.

The footnote 2 link doesn't actually work for me, for whatever reason.

What does it say?

"Arguable, since you just loose security over /root, which is not a big deal if someone already gained access to your machine, at least for me."

It doesn't render for me either, but is in the HTML at path...

.../html/body/div/div/main/div[3]/div[6]/div/div[2]/div/p

Edit: SIP has a series of control bits for a diverse set of protections. You can see what these control (and which bits "csrutil disable" toggles) in this include file: https://github.com/apple-oss-distributions/xnu/blob/f6217f89...

The link or the footnote itself doesn’t render for you? It renders on mobile Safari, just by scrolling to the bottom of the page.

The footnotes appear to the left of the main body of text around the position they appear in (viewing in a desktop browser). The article has grown a third note in the meantime and these are all visible now.
