*Entirely abandoning.
Ford no longer produces any sedan models [0].

Hatchbacks seem a lot more practical than sedans with no obvious downside. I can see people preferring the looks of one or the other, but neither is objectively prettier.
In general people looking for a practical car in the US are often buying a crossover, SUV, or pickup truck.
I think you’re right that SUVs and crossovers are taking over, from both sedans and traditional hatchbacks.
It must just be fashion, as SUVs don’t have any real advantage -- most people never do any off-roading or haul large sports equipment, and most “SUVs” wouldn’t be up to the job anyway.
SUVs are basically hatchbacks. I currently own a hatchback (GTI) and our old SUV was easier to get into and out of. The GTI is more fun to drive though.
Some people prefer a separate locked trunk.
In addition, small hatchbacks often tend to be designed as 2-seaters with a vestigal back seat as a way to maximize the use of the hatchback for cargo. As you get bigger you get something more like an Outback wagon or (increasingly) a crossover of some sort.
A hatchback is the responsible choice for for a family car, and therefore boring by association.
I realize this thread is about Teslas, but still folks are referring to non-Teslas here as well.
Maybe 3 will (hopefully) become associated with Tesla in the future and not BMW 3 series cause they are a dime a dozen in major metro areas.
I think that is a US-specific thing.
For some reason US customers prefer sedans (maybe some of the reasons given by other commenters) and that has probably skewed the market a bit (e.g. hatchbacks are only sold at higher trim levels since they’re marketed as a niche product).
Edit to add: and maybe there’s a feedback effect too? Hatchbacks are more expensive because they’re less popular, so then they’re less popular because they’re more expensive.
Given that Ford is largely abandoning sedans, it would seem that they're not particularly popular anymore. The Leaf and Bolt aren't all that weird looking for hatchbacks. Original Leaf had some weird-ish features (like the headlights), but mostly had a similar profile to the Nissan Versa hatchback. The new 2018 model is very ordinary looking. The Chevy Bolt has a pretty similar shape to the Chevy Spark.
It's not a very sexy shape, but it's a practical one.
