What activity? Paying Apple to make Google the default search engine? The search engine that 90% of people have willfully selected as their search engine of choice years ago?It's not meddling here. Allowing wealthy, powerful, dominant companies like Apple and Google to have agreements that help one or the other maintain or increase their dominance can be an antitrust violation and these types of activities need to be investigated, litigated, etc. by officials.
If there’s no harm being done to the consumer, it’s gov’t meddling. Trust me, if a superior search engine comes along, it’ll displace Google on Apple devices without any gov’t meddling.
