Who are MPLX competitors?

I'm curious to understand the competitive landscape within the industry that MPLX operates in. Can you elaborate on who some of MPLX's key competitors are? Are these competitors established players in the market, or are there any new entrants that are posing a significant challenge to MPLX's position? Additionally, how does MPLX differentiate itself from its competitors, and what strategies does it employ to maintain a competitive advantage?
