3DPrinting

All of them except the Prusa. They are all proprietary schemes to get you to subscribe to software. There are hacked sub par tool chains to attempt to use them freely, but no one really does it in practice enough that you see them using the thing regularly.

All high resolution displays are proprietary and completely undocumented publicly. Every display is different in how to communicate with it and they change constantly where reverse engineering one will do nothing of value. The next batch of displays manufactured will change in some fundamental way that means the previous reverse engineering efforts must be redone from scratch. Reverse engineering displays and their protocol is a PITA and usually ruins a display or few. You need complex jigs to handle them outside of their final packaged assembly or things break extremely easily. I've messed with some smaller simple graphics and LCD displays and reverse engineering, and it is not fun. So you're unlikely to ever see one of the proprietary resin printers reverse engineered for use with open source software. So full ownership is not an option. It is basically just like bambu but worse. As far as I'm concerned, the Prusa is the only resin printer for sale because I am not for sale/exploitive manipulation, or renting stuff for a one time payment of an equivalent cost of ownership. The Form Labs stuff is probably the prosumer level go-to.
