My goodness. I don't think there is any business-generating scam going on with adjustable flow restrictors.

Can you adversely affect your system if you don't set it correctly? Sure.
Can you adversely affect your system if you set it wrong purposefully? Sure.

Can you get peak performance out of a system with a correctly adjusted flow restrictor? You bet.

Adjustable flow restrictors are not a good choice for a point-of-use system where the operator wants to set it up and walk away (like a typical drinking water set up under a sink). They can be a very good choice for a hobbyist.
