Today there's a notice that the app will be shut down on May 23 to be replaced with a lousy dumbed down app. Which has ads.
I believe that the coming shifts to protect privacy rights are good for citizens. I don't think the internet will behave the same on Friday May 25th as it has been. I don't know if this weather application shift is due to to the GDPR: my suspicion is that the Weather Channel brand is winning and they only wanted to deal with updating one of many apps.
The best hope is that random websites will just have blank spaces instead of ads because the webmasters did not get around to updating code for the ad networks. That would be a lovely outcome.
