Re: GDPR - is a standard - it will have a logo
The apps and the app stores will change with GDPR
With GDPR will come a standard along the lines of "GDPR compliant" - probably with a better name.
An app that is compliant to GDPR will carry a clear logo to make it clear to the propspetive user that it meets GPDR requirements (in the same way that have "HD ready" TV). Then when we are in the APP store we can choose only accept apps with the GDPR compliant logo.
There will still be apps out that are not complaint - but users will download those non-compliant apps at their own risk. The download rate for these non-GDPR compliant apps will plummet. The store owners will be made responsible for ensuring that no-apps advertise a false GDPR-compliant labels.
The business model for all these snooping apps (In Europe and the other 100 of countries that copy the EU data protection standards) becomes breaks.
This will impact the users and the apps in north America too. If you are a well educated or wealthy US citizen given the choice of downloading two similar apps - and one is marked one marked GDPR-compliant what will she do? Even in the US GDPR is going to have a big influence and correct badbehaviour.
Many of the non-GDPR app providers and trackers will go out of business. The world becomes a better place.
