"Ripping off", unless you're just referring to the name of the juice, is kind of a misnomer I think. If a vendor is just re-labling already mixed wholesale-bought juices, or dumping Dekang pear into a bottle of Dekang raspberry and calling it Peary Berry Poo that's unimpressive, like calling Rum and Coke a Last Croak and not telling anyone what's in it, and being all mysterious, but not precisely a ripoff.
If I buy a vg/pg mixed nic base, which anyone can do, and simply add FA cinnamon bun flavoring and surose, which anyone can buy, I can surely sell it as My Secret Sticky Buns, and people will love it or hate it.
If I use a recipe that combines food flavoring from several flavoring companies from the DIY recipe book I can surely give it whatever name I want to and sell it - there's no copyright. Arguably, everyone should get to taste this previously unnoticed wonder.
If I make up my own amazing combination, I'm still just using flavoring and ingredients that I've purchased - it's not exactly "my" Bavarian Creme Bacon Bwaha if I just mixed those flavorings (and names) together and add 'Bwaha'. But it also kind of is. Just because some flavorings have straightforward names, like 'chocolate', and some don't, like hypno, doesn't seem to make any difference to me.
Now, if I extract my own flavorings, which a few vendors say they do (they refer to "my manufacturer" when discussing that process - I don't think they're in the kitchen with a copper boiler and cheesecloth and orange peels) and doing all sorts of calibrations to test and balance all ingredients, then no one will say I'm ripping anyone off. I'm currently really, really impressed with a juice that's produced that way.
I may be stating the obvious here, but there's a lot of fun mystique around this process and when people find out that it can be awfully simple they feel cheated, I think.
That said, I'm a terrible DIYer and nobody would or should buy the guk I've assembled thus far. With all of this legislation looming, I'm thinking mebbe time to get that act together. darkhood's Super Easy method encourages me greatly.
So hm, did I miss the point here entirely?
