This is all an extremely broad generalization of folks that vape (specifically Americans and the former colony known as Sweden). There are cloud chasers and low power folks everywhere. Some of us jump from MTL, to DTL and then sometimes create atmospheres and then explore all the types of vaping in between. Speaking very generally when someone gets into something they will eventually want the best of whatever it is they are into and there is a normal progression for it.
It goes like this:
When someone starts with something they go with the lowest barrier of entry to get into it.
Once they have exhausted the limits, ruined their cheap whatever or are missing something or a deal breaking feature exists that they don't have the road to better begins and continues until a level of personal satisfaction is met (which in the vape world is an ever improving, non existent, moving target).
In knowing this basic human behavior people make shit that is desirable either in function, aesthetics or both and people buy it at a premium because it checks all the boxes for them. Hence nice, or sometimes well marketed garbage that looks pretty and/or stuff that is made from premium materials and built to a higher standard are produced.
People at the later phase tend to get drawn toward this kind of stuff naturally. People with more money also tend to favor higher quality items because they can afford them. Whatever the reason the market dictates the manufacturing. If people are willing to buy something at a set price, people will make it for them and it will sell until it doesn't and they stop making it.
With all that said there is apparently a thriving market for folks who want mid power devices that look nice and cost a fair penny. These people obviously exist in a pretty sizable quantity or the product wouldn't be made.
