That is not the case. The "right to be forgotten" is not absolute. There are lawful bases for processing under which the right to be forgotten does not apply.
Go read GDPR article 17.3, it's easy to read. A few things for which the right to forgotten does not apply:
- exercising the right of freedom of expression and information
- for compliance with a legal obligation (e.g. keeping records for tax reporting)
- for public interest reasons related to health, science, historical research
Seriously, there is too much FUD about the GDPR.
