I remember avocados from the 90s as being rock hard and mostly flavorless. Perhaps they were better locally, but I never had a tasty, buttery soft avocado until the 2000s.
Almost all fruits and vegetables in the US taste better on the US West coast, in my opinion, and I suspect it’s because you’re closer to the origin (Cali/Mexico/WA/OR/the rest of Central and South America) so the fruit/vegetables take less time in transit and therefore don’t have to be picked so early.
Avocado also varies based on weather and age of the tree.
You can’t reasonably compare unripe produce transported from 1500 miles away with fresh ripe local produce.
Avocados exported from California to the East Coast can also end up mediocre.
I also cringe when I see people pressing their thumbs into them at the store.

This is a very pronounced effect across all sectors of the economy. It's really not that surprising. It's similar to the old traffic engineering adage that expanding highways expands traffic in equal measure - such that it is often futile to add extra lanes to existing congested roads.
When something becomes cheaper/easier to use, demand often rises to the point that the new equilibrium is similar to the old one, as new opportunities open up to use X product that were previously unexplored due to constrained supply
Maybe that's true for the ones shipped eastward.
Here in the SF bay area, I find California Hass avocados are superior to those available from Mexico and Peru. They're easy to peel and the flavor is fantastic.
That shift has laid the foundation for items like avocado toast or Chipotle’s guacamole to help popularize avocados.
There are lots of other factors, I’m sure. But it helps that they’re tasty.
My understanding is also that it can take 20 years from pit to fruit-bearing-tree, so supply will tend to lag behind demand (which has grown globally.)
No one answered you about avocado toast, but it's literally what it sounds like. Slice some avocado, put it on toast, typically with a poached egg and some seasonings of choice. It's seen as a quick healthy meat free breakfast or lunch that still has a sort of richness to it. It became a fad with younger people after restaurants realized it could be a real money maker.
By contrast, oranges aren't something I'd indulge in. They have much more sugar - ~10x what an avocado has. They're acidic. They're not particularly filling (low fat / protein content).
I too was also lucky enough to grow up with a hand full of avocado trees that fruited every year, and I say that even though I never really cared for them personally, but to this day I do incorporate avocado oil into my salads and wish I had acquired the taste for eating the avocado itself.
I think the marketing has died down but for a while I Felt it was almost on par with the kind of submarine marketing both pizza and tacos get as a favorite food of the masses.
I stopped eating chips with canola oil and only get the ones with only avocado oil, because the canola is rancid for my belly
