Lego violates GPL by keep Blender-based BrickLink Studio source closed (2021)
The MindStorms bricks were based on Linux, but they couldn't care to even provide a text-mode uploader for new firmware that worked on Linux. Happy to take from, but not to give back to, the community. Their support didn't even understand the bug reports in the firmware when spoon-fed. No engineering left; just plain money-grab at this point.
