I'm always perplexed by these vague but very consistent comments about burning taxpayer money. If you think government actions are a waste of tax money just go live in a forest or something.
Even if it is free it's still an essential service that we all use. The consumer needs to be protected from monopolies that harm the market. Monopolies have been proven over and over again to be harmful to the end product. Imagine if Google actually had competitors. They'd actually work on improving search results which everyone has been complaining about later. They wouldn't put 5 ads at the top of the page. They wouldn't rank lengthy, vague sources at the top to maximize your time looking on their ads. How can this be a waste of time?
To be fair, the data is easy to cherry-pick and manipulate: it's probably pretty easy to plot Facebook against enforcement actions and say the enforcement actions led to a stock rebound (instead of cost discipline)
If the MS litigation of days past is any indicator, this will do exactly nothing other than burn taxpayer money.
