The main text is black yes, but anything that's bold is light grey as per the CSS, which is near unreadable (even if you're not as colourblind as me I suspect)
Unrelated to the content: why on earth is super-light grey a good "bold" colour for a white background? I'm having to highlight each of the bolded parts of the text just to understand it :/
edit: console command for anyone else struggling to read this `document.documentElement.style.setProperty('--bulma-strong-color', '#000');`
From how I read it, the author seems to be suggesting that this list of IPs be on an allowlist as they see Google as "less nefarious". As such, sure, allowing google IPs is as easy as allowing all IPs, but discerning who are "nefarious actors" is probably harder.
A more tounge-in-cheek point: all scripts take an LLM ~10 seconds to write, doesn't mean it's right though.
