After reading through the ensuing chaos, my original points stand firm.
Also, I might as well jump on the "clones on this forum" bandwagon.
I think they're in a grey area. If they are being promoted (and recommended to others), no (on a case by case [no pun intended {oh God this parenthesis nesting}]). If they are simply being used for a build and then showed off, I would say OK.
[SPOILER="Trying to lighten the mood..."]
From now on, I have made the executive decision to embed proprietary systems within my files and my designs to prevent people from successfully taking the product apart and replicating it by adding weak (on purpose) attachment points that require precision to remove and that will break if they are tampered with. Additionally, I will add compact servo motors to designs to shift parts of the design by a proprietary number between 1 and 1000 millimeters every hour, to completely prevent an accurate measurement of part size. Finally, each design will be embedded with a digital and physical tracking device made custom out of proprietary atoms within the air bonding with a laser cut to produce an electronic system capable of tracing location. If a device is shipped within general vicinity of any minor or major industrial district with manufacturing capabilities, servo motors embedded within the box will destroy the design immediately and effectively. Cameras will also be embedded within the box to check a proprietary set of proprietary micro-coded angles in proprietary units on a proprietary location within the design. If those angles are not complete (due to the inferior capabilities of laser cutters compared to proprietary manufacturing), the design will also disassemble.
Oh, and I will have control of a "panic" button that will make all e-lab designs on the planet fire proprietary lasers at proprietary alternating angles from 90 degrees south and the nearest inhabitable galaxy, encoding a message in proprietary Morse code that reads (encrypted under hexadecimal then proprietary codes) "{insert proprietary message"} (most likely "no u").
You know too much now. I guess I'll have to put you under a proprietary trance.
This is a jab at Apple's new anti-repair system and a joke about preventing copying, by the way.
Cheer up, people
