As for the revenue – there are certainly cool opportunities to run relevant ads when you have high levels of attention from someone and their close friends (think group experiences, people buying things at the same time that their friends, etc). That said, we don't like what ads have done to current social platforms. They misalign incentives where the more money the product makes, the worse the product tends to get for users. Snapchat was pretty fun until it went from only seeing friends to seeing celebrity gossip and repetitive ads. Because of that, we're planning on doing a subscription model down the road, similar to what WhatsApp tried out before it got acquired (first year free, then a small fee.) Certainly a new model for a social app, but we think it's the best direction for us long-term.
Lets say, you gave your card automatic monthly billing to company 'X'. You would normally expect that when card expires, it won't be billed anymore and they will ask you for new card details. The reality is company 'X' goes to credit card company and tells them "We have these card details with us. Everything except expiry date is same. So you can conclude that we legitimately obtained the card details. Can you give us the new card details. We will update the account accordingly. It is even useful to the customer as he will be (cough cough) inconvenienced."
I think something similar happened in your case. Source: I implemented this in a big e-commerce company(Not AMZN).
