You may consider them trolls,....
I'm sorry my friend, I think you misunderstood me.
I wasn't referring to "them" as the troll.
But to be serious, it would be a veritable "crud storm" for a company to throw a cease and desist order on a fan of one of their products. Word would get out that Brand __________ is throwing out threats at their customers. And the legal cost? Sure lawyers on retainer are already paid for, but the costs still pile up, because you know the old adage, "time is money". In the end, any sane business would know it would be shooting themselves in the foot with such bad PR.
Look at an example: Disney. Disney owns Marvel and these fandom conventions that come around all the time is awesome PR for the company. Now, imagine Disney getting all snooty over people dressing up like Spiderman or Captain America. Is that copyright infringement? Sure is! Another example is CBS and Universal Studios getting all uppity over Star Trek fans making fan-boy YouTube videos. Sure, I think ST:Axanar did cross a line: they raised money to hire professionals, but the crud-storm that followed .... CBS and Universal are still reeling over it!
If I owned a blending company and I saw such activity, I would look into it and see if any profits was being generated. If not, I would reach out to the web site and remind them that my business logos were on some of those labels and that they need to make sure no extemporaneous profits were being made. If my company and that website were on the same page, then honestly, I would provide some better resolution clip-art for their members! Like I said, free PR! Matter of fact, I do know one or two companies who have done this already (I'm looking at the great folk at The Country Squire who provided clip-art to another label designer. Kudos to you!)
Would I delete any label owned by a company that asked me to delete it? Sure, but I would make very sure enough of my BotLs would be included in the news. People just don't like jerks, and such actions by a big company one a small guppy fan... well, it usually leaves a very BAD taste in everyone's mouth and associates their products with a foul money-grubbing company.
