If I had to guess, this chart lines up pretty well with the adoption of smartphones, so I’d say the drop is due to people using the default Android and iOS browsers on their phones. I’ve installed Firefox and use it on my phone but I don’t know many people who bother changing from the defaults.

Probably doesn’t help that Teslas guess which direction you want to go in and you have to change it if it’s wrong. https://www.autoblog.com/2021/01/28/tesla-new-gear-shifter-guesses-direction-you-want/

While fucked up, it’s disinguinuous suggest that the news is blowing up only due to the fact that they’re billionaires. While large boat disasters are fairly uncommon, how often do you hear of a submarine disaster. Especially one where the inhabitants are missing but potentially on a timer - trapped in a submarine with no way to open from the inside, many peoples ultimate fear. The story writes itself, pile on what seems to be a neglectful company and you’ve got a story people are going to be invested in. I don’t think the coverage or the search and rescue would be any different if it were a scientific submarine with scientists.
