I am not speaking of you specifically because this is about the behavior of companies and not personal projects.

There are companies, OP being one (a subsidiary of Pinterest) that have presence in the EU and are essentially playing chicken with the regulators. Blocking users but keeping their data is not compliance, nor are dialogs telling users you plan to carry on as normal. Companies do not do this with the IRS because they would be afraid of the consequences.
