I suspect you are right right in mentioning single serve waste producing machines.
I think there has been a greater split between those who tolerate crappy coffee and those who don’t - the crappy coffee people have moved to the expensive single serve machines, and the people who are picky grind at home (and probably also don’t buy at the grocery store). The rest evidently use pre-ground.
The gap between commodity coffee and snobby coffee has grown, and the availability of snobby coffee has grown between the multitude of roasters and online shopping. If it’s, say, $10 for a bag of premium coffee beans that’s of unknown age (at least 2 months) and lists only “south American” as its origin, or $15 for a bag of 3 day old locally roasted beans from a specific farm in Colombia, I’d go for the latter. I think my prices are a good 10 years old, but let’s just use it as an example.
Ironically the k-cups are quite a bit more expensive than that.
The in store grinders are still around in some stores.

Bags / cans of pre-ground is also on the decline in my neck of the woods. The exception being pods. Half of my coffee aisles are pods.
I feel like most people are in one of two large camps. Whole bean people with grinders or self grinding machines, and pod people.
The pre-ground bag / can people are an increasingly small slice of the pie.
