As discussed in "The Age of Surveillance Capitalism"[0] it's inconsistent with their business model for Google to comply with GDPR and other similar privacy laws/regulations.
The benefits of the surveillance capitalism business model are seeing business values being recalculated as business owners recognise the value of exploiting vast amounts of data collected in the pursuit of a purpose other than for which it was collected. Microsoft for example has been heading in this direction over the last few years through their acquisition of Lynda/LinkedIn, Github and Glint. I expect other SaaS businesses to increasingly exploit this opportunity.
Personally I support the efforts of Brave in this case and there are other potential targets that I think are vulnerable to a similar complaint. It will be interesting to follow the Irish Data Protection Commission's progress on this.
