> none of the three things you mentioned are anywhere close to monopolies. I think it depends on what you consider "the market" to be. If I want to compare Amazon to the "Global Retail Market" (Amazon's preferred framing), then maybe they aren't in a monopolistic position. But I—as ab individual—don't participate in the Global Retail Market. I participate in the "online US retail" and "Pacific Northwest retail" market. So I don't get much benefit out of there being more competition to Amazon in France, so the "Global Retail Market" doesn't seem like it's always the right framing. For me, it's still the case that Amazon doesn't feel like a monopoly, but I could imagine areas where Amazon is much closer to being one of just a small number of options for many products. Similarly, I'm sure Facebook wants to be evaluated against _all_ communication media, but again I want to communicate with people in my immediate network. If 100% of my social network and business contacts used exclusively Facebook for communication, then from _my_ perspective Facebook might have a monopoly on my communication options (even if they have real competition in China from competitors). I'm not so convinced that we should just accept the broadest possible interpretation of "the market" that we should evaluate as the correct framing. From the perspective of some individuals, if there is only a single dominant option, then that person still needs to deal with anti-trust issues. It's similar to the way some of the major internet players will carve up the country into regions of fairly exclusive offerings. Across US broadband, the market may be divided amongst a number of different players such that it doesn't appear to be a monopoly. But when you zoom in to an individual municipality, it might be that there _is_ a monopoly at that level, and the competition that appears to exist in the "national market" is actual a union of separate monopolies (and other regions where there is actual competition). So, while I totally agree with you that under the legal definitions of monopolies, many of these entities are not there, under individuals _practical_ definition of monopolies, many of these entities _are_ monopolistic.
