Sure I'm certain that is the endgame for Bambu, but I'm also sure that people won't stand for it as long as there's any kind of competition (of which there's currently loads) and will move to the next best thing. They've come out of nowhere and captured the current gen, for the next one we'll probably see someone new.
I don't really buy the longevity angle for something that's moving so fast in terms of tech, my old Ender 3 lasted long enough to make itself obsolete in practically all aspects with practically zero maintenance. I had to junk a perfectly working machine because it became something not worth putting filament into. With such improvements each gen I'd rather have a cheaper machine that runs for a few years. Maybe we've already peaked but I seriously doubt it. I wouldn't be surprised if we see non planar antialiasing as stock at twice the speed and half the loudness, making what we use today once again become a waste of filament. Disposable low cost crap makes a whole lot more sense imo.
Remember the first gen Makerbots? Horrid overbuilt machines with glass beds, mandatory raft, quality barely worth a mention. They cost 5k and were obsolete in like two years tops. That's roughly how I see Pruša's approach as well.
If we actually valued local skills in the EU we'd have subsidies that make them competitive, ergo we do not. Personally I don't really see any for-profit surviving past going into the dark pattern hole eventually, there's too many incentives. Best just take what's best and least locked down today and run with it, assume it will vanish tomorrow. Forget long term support. Luckily there's always someone else willing to burn VC money in the initial market flood phase lmao.
