UPDATE: And this news website even detects if I use incognito mode: "To continue reading, please disable private/incognito mode, log in, or enroll as a member" omg
I was able to eventually get past it using ABP by adding rules to block https://courier-api.dallasnews.com/v1/paywall/* and www.dallasnews.com###courier-iframe
But the article is very light on details
(I am surfing from the EU)
Its also not free. Rational companies will apply a cost benefit analysis to GDPR compliance and some of them will determine it is better to block EU visitors than to do the GDPR work.
This is a real cost of the GDPR. If enforcement ticks up more companies will do the cost/benefit and some will decide to withdraw from the European internet. That leads to a more fractured web.
If you think there's a compelling business case for enabling European access, you may wish to contact the publisher.
If I were running this site as a business I would need to evaluate how much it would cost to bring, and keep, the site into compliance versus how much revenue I derive from European visitors. Don't give me the "it's simple if you aren't tracking people" line, either. It's not simple, and I'm not going to trust the health of a business to the interpretations of random Internet posters or the benevolence of regulars on the other side of an ocean.
I'm not defending the decision, I'm just providing a possible explanation as to why businesses, when faced with GDPR might choose to block EU users.
