So they just use HP inkjet technology. That makes it less open-source, but even "open source" parts are going to be under non-commercial license (CC BY-NC-SA) anyway.
Remanufactured cartridges for these printers are available. They profit from the first use of the cartridge, but make nothing out of the refilled ones (I've been using them for some time now).
You still pay for it to the company that has decades of hostile practices towards their clients. Their mechanisms are so bad that they even disable valid original cartridges sometimes, good luck with getting that refunded.
But maybe I'm emotional, as that company has been taking premium for a broken experience of so many people I know. I didn't expect such project going for their equipment.
Is there a Linux server run on fully open source hardware (what would that mean btw?)? Should we stop using "open source" because almost all computers are not fully open source?
Quite a lot of open source hardware is licensed under the BY-SA Creative Commons license which is an actual open source license. E.g. the Arduinos and things like the Milkymist One which can actually run linux.
What are you even trying to say? The fact that this is hardware isn't what makes it non-open source, there's plenty of open source hardware out there. The thing that makes it not-open-source is that the license is non-commercial.
If you can't legally use the product, the fact that the source is available is meaningless. CC-NC is a source available license, not an open source license.
No, it doesn't: I can build a machine described in an All Rights Reserved book. CC BY-SA-NC grants additional permissions on top of that, but it doesn't remove any. You're thinking of patents.
