GP didn't say they didn't want to enter their email because it's a risk. My reading was that it was another hoop they had to jump through to do their diligence, reflecting on what the company thinks of their customers the same way the NDA requirement itself, and the IP clauses do. I'm not sure how the connection to money or capitalism comes in here.

Funny how you frame this like it's a problem for the customer. The business needs customers to survive, the customer does not need the business to survive. The customer is in the business of giving money to people who aren't going to abuse their data. If you can't cross that low threshold, you're more trouble than you're worth as a business, and you're not getting paid. Isn't capitalism neat?
