I don't think this has a lot to do with the open source spirit but the fact that competitors like Bambulab are eating their lunch. That seems to rub them the wrong way.
I also see a lot of FUD from the Prusa community regarding that particular brand, where you can't claim it's a 1:1 Prusa clone. Even the remarks from Josef Prusa about speed or noise are targeted to the X1C or P1P printers while if you want to talk about clones and copying there are brands out there that fits the bill better e.g. Sovol 06.
The part where you can only sell "consumables" that must be verified by Prusa also has zero to do with open source or freedom.
