Sometimes a writer will use what they feel is a more recognizable but 'technically incorrect' word as a colloquialism for a less-used term that's more accurate, and then go into more detail in the article, but it's good and proper to wrap that colloquialism in apostrophes ('air quotes').

But in this specific case, it was ruled that Google has a monopoly on general website searches and that they have utilized a variety of anti-competitive practices to bolster their presence as such.

Not dissimilar to Microsoft's antitrust case in the late 90s, specifically regarding Internet Explorer. It was a very small chunk of a much larger antitrust suit but they were found to have used Windows in order to stifle competition for web browsers and maintain their standing as the dominant browser (they also leveraged their market share for Windows and IE with OEMs and ISPs respectively but I'm digressing).

Microsoft was ordered to split, or spin off their browser business into a different entity, but they settled with DOJ on appeal (probably what we'll see come of this - Google will probably make a big long list of things they will change or no longer engage in, and the government will feel as though all those changes will be sufficient remedy)
