Trying to force people to use a cloud account just to get functionality of the piece of hardware they already paid for with no technical reason behind it whatsoever is ludicrous.

There is a technical reason behind it which is integration with MakerWorld and being able to browse files from there and send them to the printer remotely from your phone or other device.

Again, I won’t argue against the whole privacy aspect as I get it, but I just don’t really think it’s a big deal or something of consequence if we’re simply talking about 3D prints. They do have the option to use them locally now, but apparently this doesn’t include all their models (which you may have mentioned already or it was someone else).
