Yep, I’m pretty sure you can still just use spools without tags and then manually set the filament settings, but since they control the firmware and can block downgrades, they can at any time require RFID tags for it to print. And since the tags have proven to be mostly cryptographically secure, that leaves open an avenue for them to lock out third party filament. It looks like you can currently clone the tags, but in theory they could program them like printer cartridges where it will recognize when you’ve printed a full spools length from any specific RFID tag ID, and then block printing using that tag ID. That could make cloning the tags useless and force you to only buy bamboo filament just like HP and printer companies and their ink.
