Google antitrust just latest in series of battles with big tech.

Google illegally used its search engine superiority to monopolize online searches to stifle competition, a federal court ruled Aug. 5 – a decision that may be followed by others as regulators seek to limit the reach of big tech companies.

Dozens of states have joined federal antitrust suits against “Magnificent 7” companies Google, Amazon, Apple and Facebook’s parent Meta.

Google, with its parent Alphabet, is being sued for online advertising practices. The company is appealing the Aug. 5 search engine antitrust decision.
