Before the GDPR almost no company gave me the option to delete data collected on me, download the data they collected and companies did not have to disclose what third parties they share info with or why. That's a big difference. I've worked at companies with large web presences and I can honestly say that having the GDPR meant that we collected a lot less data about visitors since we had to justify it before collection rather than just seeing if something interesting came out of it.
