What Hacker News says

Speaking about Prusa, my experience has been that they’re very condescending to users. Extremely basic features (like serial printing) are considered “nice to have”. Some tickets have remained open for over 6 years now and ignored by prusa: - https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/189 (still open after 6+ years) - https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/283 (took 3.5 years to acknowledge and fix)
In Louis Rossmann offers to pay legal fees for a threatened OrcaSlicer developer
I have a lot of respect for Armin, but it's pretty clear he doesn't really understand the specifics of what he's talking about here. > people are complaining (The MK4 firmware is not Open Source) the link here is to a reddit post (https://www.reddit.com/r/prusa3d/comments/10g6fgv/prusa_givi...) in which the complaint is not only not about the MK4's firmware, it's also not even about something not being open source. Specifically, that complaint is that PrusaSlicer (the software which turns a 3D model file into GCode instructions for the printer to follow - think PostScript, but for a 3D printer) is not developed as an open project. PrusaSlicer is open source, but most of the development happens internally at Prusa. It's a legitimate complaint, but not at all the complaint Armin claims it to be. For the record, the Mk4 firmware is also open

In Why Prusa is floundering, and how you can avoid their fate
The Prusa mini has an ethernet port, so people assumed that you could hook it up to your LAN and print over the network. As far as I can tell, that doesn't work yet, and the Prusa website [1] says: > Full control of your printer will be added in future releases Edit: It looks like remote printing was released in a Firmware update in Nov 2022 [2] and the documentation website wasn't updated yet.

In Original Prusa MK4
Why would a bootloader ever be considered part of the same program—they don't even ever run at the same time. Also, this person (https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/1440#...) misread the GPL, when they said this: > but the license clearly states that it is not an aggregate if they are combined to form a larger program in or on a storage or distribution medium The GPL very much does not say that: > which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate”
In Where is the source code for the actual bootloader shipped with the Prusa Mini+?
