Most people do not care because they don't really see/understand how it affect them. Just like most people probably don't care about HVAC regulation, welding regulation for system under pressure and other very technical field.
They will see the issue and care about it when something happen. We have a lot of regulation about welding under high pressure because we know from experience what happen when we have no rules (things go boom).
What happen when we have no regulation about tracker ? We get massive data leaks from poorly secured data hoarding company (hello Equifax). This is dangerous in many many ways: Identity theft, scam & spam, identifying people with certain political view, from a minority of some sort, etc...
GDPR does not solve all this issue, some company can still hoard massive amount of data about you (it is always scary to ask for a data extraction from Meta, Twitter, ... and how you have a "profile") and have bad security, but it does limit in how many hand this data circulate and how easy it is to gain access to.
