The list of companies that have tried "simple, general purpose" is long and sad:
Celestron
Meade
Orion
...many more before that. "Easy to order, everything included" wasn't enough. All these companies stopped investing in technology and fell behind. They could not sell enough with their business model to survive. They never cracked the code of making it easy and fun, out of the box, for the average person.
Someone mentioned the Astroscan earlier - seen as a wonderful/elegant beginners scope at the time. I have one. Bought it for my kids to try when they were young. It's actually pretty terrible. Tiny mirror. Bad views. Hard to use. Frustration in ball form.
The challenge with the hobby, for beginners, has as much to do with the changing nature of people, their expectations, and their natural environment as anything else. The hobby can stay niche or it can evolve to meet people where they are going. The solution will likely be "just enough" technology to increase the immediate bang-for-the-buck, and to make the hobby less complicated and challenging - with an easier introduction, and requiring less dedicated time.
After they are hooked, there is plenty of opportunity for niche providers of big scopes, complicated setups, etc.
