Welcome to our forum.
See that's freedom of speech, it's harsh and a little angry but very free.
I think the best way to counteract all this is by doing exactly what you, Chas, Stuart, Mendo and the rest of the professionals have been doing: offering (almost )unbiased information and assistance to us consumers. I am certainly more inclined to give your brands consideration when it comes time to replace my spa, and if any of you were in my area, your dealerships would be on the top of my list. The goodwill you generate more than offsets any publicity they are getting.
If I was a conspiracy theorist I would say you all started the original post so you could respond with this to sell you own tubs...
