The previous right to be forgotten was limited to only search engines operating in the EU. Meaning, google didn't have to remove the data itself, just the entry to the link in the index. GDPR is far more onerous in that it applies to all data processors everywhere.
"The ECJ ruling only enforced the right to erasure on search engines operating in Europe. The proliferation of personal data that is available online extends far beyond their indexes. It's often exploited for the benefit of others, and their motivations may be contrary to the wishes of the data subjects. It will now be extended to all data processors."
