I think the derision illustrates a low ethical floor in the industry. Intimidating users with legalese is standard business practice, for instance in user agreements. The fearful effect it has on the less knowledgeable, competent, and resourceful among us doesn't even seem to register. It reminds me of abusive sales techniques that victimize seniors, and the salespeople who chortle at the stupidity of those who get taken in.
Abusive sales techniques aren't just for the elderly, if you've ever seen a car dealer sell a Dodge Charger or similar to a gullible US military E2 at 22% interest on an 84 month term...
You're absolutely right. I happened to be thinking about specific distressed elders in my life who I have had to talk down because they are worried about getting scammed, and the emotional toll it's taken on them. Not everybody has enough expertise to navigate potential scams reliably and with minimal stress — such expertise exists on a continuum.
