So do you purchase off your own back, or do you buy what you're told to buy? There's good and not so good in any industry, with any product type you buy, but at the end of the day, you have the ability to view and experience before parting with your money. If you buy a **** car, that's your fault.
All this 'don't buy this product if the SINAD is above this number', 'this is awful', 'this is poor' etc etc is just conditioning viewers to ignore products which very likely sound extremely good, and could be the perfect product for them. I'll make recommendations to people (if they ask me to), but it's not based on distortion numbers, it's based on their system suitability, personal preferences, and in some cases, room suitability. The sheep are hanging on his every word, waiting for a product or brand to attack, so they can puff up their chests and give their keyboard a good banging.
