It's not about # of customers. Even apps with billions of users can survey those users, or use some sort of a/b testing to figure out what impact any change to a product will have. The issue is just that sometimes a change might be good for new users only, or might be good for some metric the business cares about that you don't (ie maybe the Economist needed daily actives instead of weekly actives for some reason so they launched daily news). Not saying the changes are always net positive, but I don't think it's a simple as "they want to get promoted and can't talk to all their users". Also, as much as I love AWS as a service overall, it's actual user experience is pretty terrible and I wish it did change over time (for the better).
