How is making it seem like the data is mandatory any better than it actually being mandatory? I will probably bounce as a customer either way before actually in detail investigating the huge form I was presented and buy from an online competitor or from a physical store.
And maybe I am an odd customer, but I also think that the customer who buys more sneakers just due to a spammy newsletter is too.
Edit: Online casinos here in Sweden recently went through a revolution where they added e-ID login (meaning that users do not need to complete a huge form on signup) and automatic withdrawal on logging out when possible. Sure, they were lucky that they could get almost all of the old data they gathered by using the e-ID, but even if they had not been able to I think it still would have been worth it to collect less data to get more sales. And apparently slowing down withdrawals was bad for business (who could have known!) despite making some gamblers lose their money while waiting for the withdrawal to be approved. Customer hostile greedy strategies can trap you in a local optima.
