Would OP/Richemont seek legal recourse for IP and copyright infringement from a small bunch of fans provided no money changes hands? Probably not but the point is they could!
Would OP/Richemont have an issue with someone producing a few hundred care stickers that they were going to give away...again probably not but the point is they could!
I agree that in the essence of what normally happens within this community then the owners of the logo design/device and it's IP/copyright have not persued any legal protection etc to date...but again the point is they could
But what does bother me is the general misconception that it is just 'ok' to use such a logo/device without seeking permission of the owner and/or being nieve enough to openly ask on a public forum who would be interested in such an item.
Also all you need is for someone to start charging or these items and then have a disgruntled client who does not get said item or is not happy with the quality who then in turn complians to OP/Richemont. then who do OP/Richemont persue...yep the guy who asked on the forum who would want one...
