This actually happened to me after connecting to wi-fi but there is a workaround that I found:

Convert your book to .azw3 in Calibre

Instead of sending it to the device in Calibre, locate the azw3 file (Right click -> Open book folder).

Copy the file to your Kindle, but not to the "documents" folder (where Calibre usually puts it) but rather into Downloads->Items

This folder is where books go when you buy them from Amazon or receive them after using the Send to Kindle feature. I have only tried this with azw3 so far but it might also work with .mobi format.

Could you elaborate on Canada's approach? Are you referring to adjustable rate mortgages?

I'm guessing the GP means that there will hopefully be an increased interest for alternatives to planes that one can take when there are air travel crises like this.

I also suffered from this issue for a while but then discovered "Unhook" browser extension, which in addition to many other amazing features (e.g. hide recommended videos/comments) has a feature to hide irrelevant search results. With the feature on I get an endless list of matching results and no junk.
