GDPR was never intended to be "good for startups". Just like pro-climate policies are never intended to be good for the economy.
GDPR was intended to be good for peoples privacy. Pro-climate policies are meant to be good for the climate.
Somethings gotta give. People are generally more important than startups. Climate is generally more important than economy. Because without people, there are no startups. And without climate, there is no economy, people, or startups.
