After all, if someone exhibits a certain attitude towards their users' data that is a good indicator that there is more that isn't done properly.
It's funny that you think that it's totally ok to do this.
You don't need to create a specific feature for European users if you don't want to, just as European users don't need to do business with you if you don't value their privacy. Economic exchanges are voluntary. If you think ignoring European customers is something that pays off for you, go for it.
If we would not care about privacy to a greater degree than other regions we would presumably not pass legislation that protects private information and cuts into ad-revenues.
What's really being affected on the backend side of things is bulk data collection and storage and sharing with 3rd parties without consent.
