This is very close to the academia/industry divide. Academia (the public) spends an enormous amount of money investing in research to discover something novel and effective, or makes a large efficiency gain. Industry reads that, and implements it, with some minor tweaks. This, products are made for fractions of the cost it would have otherwise cost to make, with large improvements over previous capabilities, due to the work done in the public sphere. Effectively very similar to open and closed source.

To be clear, I'm not sure your analogy makes sense for the bambu printers vs prusa situatuon. If anything, prusa did not spend enough money actually advancing their tech. They are still deeply attached to their good old bed slinger design in 2023, and they literally just implemented the same thing with minor tweaks for years until recently. They rested on their laurels which was fine when the 3d printing industry was stagnating, but not anymore.

Bambu lab on the other hand came up with something pretty good, very well integrated that has basically taken 0 from the prusa designs. So it's not really closed source profiting off of public or open source work. Maybe for the slicer, but that's it.

Just compare the abysmal performance and quality of prusa's MMU that still really sucks almost half a decade after they originally released the product. Even if they are super expensive too! While on the bambu printers... It just works.
