No, they're still here, Google/Bing just don't prioritize the old web style websites that don't have trackers and don't have mobile friendly designs.
You can find these old style sites with Marginalia a search engine for the ''small, old and weird web'.
There's also an explore section if you don't know what to search for.
It's a small web search engine so there is not a result for everything (as there was in the early Internet). The 'Explore' feature is probably more entertaining (stumble upon-esque) than using it as an actual search engine.
This basically happened in Operation Mincemeat
Attached to Martin's body was a briefcase containing secret documents that had been fabricated by the British Security Service. The purpose was to make German intelligence (which was known to have operatives in Huelva) think he had been a courier delivering documents to a British general. The documents were crafted to deceive the Germans into thinking that the British were preparing to invade Greece and Sardinia, rather than Sicily.
I used to have a service which required Authy and that will not work with a failed Play Integrity API check.
Chase and AMEX make it more annoying to log in by requiring additional 2FA after fingerprint unlocks.
Capital One is the same experience as my stock OS.
