We each have the right to do what we want with our business. Bottom line for me is that Bluesky still uses the graphic identity of Shellac - it still copies the look for the purposes of deceiving either the tech or the client. It is still a counterfeit. It had to be sued to remove the word "shellac" from its labels. So, until they give up on that, I won't use them. My job was upgrading borderline NSS salons - the first thing we did was get rid of dodgy products, including all counterfeits. So it was bye-bye BlueSky and CCO! While they have both started to provide MSDS and participate in trade shows (although they have tried that for years and their products were even legally seized as counterfeit at one CosmoProf show), they still have a long way to go towards being a legitimate professional product.
As for harm done, why would you use a product that deceitfully skims off the most profitable part of the industry and does not provide education, training, customer support or marketing for professionals. We all want to be more professional, so why would you use a product that undermines not only your own professionalism, but the industry's? And let us not forget the animal testing issue!
As for being judgmental, that the role of an industry/professional forum. There are standards for being a professional, and when a group like this considers those standards violated, it is their proper role to judge. It is beyond naive to come into a professional forum and claim to use a counterfeit, non-professional product and not expect to be judged. It is your business, but others are entitled to have an opinion about it and speak on it.
