So far, full open source and standard parts have been the standard for consumer-level 3D printer since the RepRap project, and especially for Prusa.
But it is not the case for BambuLab, except for its slicer, but I suspect that's only because it is a derivative of... PrusaSlicer, which is AGPL. Because BambuLab makes great 3D printers and is therefore very successful, the community worries that it will set a precedent and that 3D printing will become more and more locked down.
