Antitrust and competition regulation is built entirely on arbitrary quantitative definitions of competition rather than reasoned and objective qualitative definitions of competition. There's a big difference between qualitative and quantitative definitions of competition. Anyone is free to compete with Google (qualitative), while Google dominates search with ~90% market share (quantitative). Even if they had 100% market share, they still exist in a qualitatively competitive market. But antitrust and competition regulation isn't concerned with that, and we've heard calls by EU regulators to break up Google based on their market share. Same with Facebook.
