For the longest time companies have been able to market something as 'free' when they have been the ones who have been trying to hide the fact that users' data was being sold, etc. So I would argue that if someone is 'stealing', it is actually the companies themselves.
The "stealing" is because they are trying to get companies to give their content out for free without paying the cost which requires targeted advertising (and no, generic ads pay shit which is why tons of companies are blocking all the EU because they now aren't worth the server costs).
If you're sick of people using your product and not giving anything in return, Charge. A. Fee.
The GDPR specifically forbids giving users the option of paying with data. (In that you can't deny access if the user doesn't agree to the data usage).
Charge. A. Fee.
It turns out that a whole lot of users don't want microtransactions for everything they do online, and would rather allow providers to monetize their data in exchange for access. You not liking those agreements is not a reasonable justification for forcibly banning them.
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.
