Bingo. When I read that part of the article, I felt insulted. People see the web getting increasingly enshitified and less accessible. The increased need for cached pages has justified the existence of 12ft.io.

~40% of my web access is now dependant on archive.org and 12ft.io.

So yes, Google is obviously bullshitting. Clearly there is a real reason for nixing cached pages and Google is concealing that reason.
