The Bambu printers, at the time of their release, were an incredibly superior pieces of hardware and software that was priced very very well and, this was a really big deal, worked fully right out of the box.
It was a pretty clear choice in either dicking around with the tools, or actually using the tool to make things. They caused a huge shift in the industry because it was silly to NOT buy a Bambu, if you wanted to actually make things.
I love open source software, but I also know that a team of focused, dedicated, high skill, engineers, who are financially motivated with big paychecks, to do well, will often do a better job making something proprietary than a bunch of volunteers doing it for fun, on the weekends. Ffs, we didn't get a half ass implementation (thanks to shite 8 bit boards everyone was using) of motion/vibration compensation in all the open source firmwares, a tech from the 1960's, until right before Bambu's release. It's still not available in most. Pressure compensation was still relatively new.
