In his answer to this question Dr. Monzer Kahf, Scholar in Islamic Economics & Financial Expert, stated,
I don’t see any Haram in selling these goods if the questioner believe in this technology. It becomes not correct if you believe they are lying and cheating people. Here you are required to avoid cheating.
But if this claim has a scientific reality, it is Ok to sell these products. The work environment is something that is no more avoidable anywhere you work in today’s world.
May Allah guide all of us to what pleases Him!
