U.S. Senator Ron Wyden (D-OR), known for raising various tech and privacy-related issues, asked for an investigation of the online ad-blocking industry for allowing major tech giants such as Google, Amazon, and Microsoft to pay to get whitelisted.
Citing anti-competitive behavior, Wyden claims that ad-blocking companies promise to block online ads but then sells whitelist accessibility to some of the largest ad companies.
This nullifies the effectiveness of ad-blockers. One of its most significant benefits is that it blocks trackers via ads, but not if it allows major advertisers to continue to serve ads.
