> leveraging your market dominance in one area to compete in another is illegal
Leveraging your monopoly to compete in another area is illegal. Leveraging a strong position isn’t and Amazon is a long ways from a monopoly.

In the EU, it is "dominant market position" (and explicitly so) that's the threshold for the Commission to take competition action, for instance.
(not trying to argue they aren't dominant. just curious)
British Airways only had a 38% market share when they were sued for abusing their dominant market position in 1998 (which was upheld by the Court of Justice in 2007)
That really depends on interpretation, which has shifted over time and continues to shift. IIRC, recent interpretations of some types of anti-competitive behavior have been rather literal and required something very close to a literal monopoly, which has had the effect of neutering antitrust law in all but the most blatant of cases.
My understanding is that it's arguable that it's anti-competitive to leverage market share advantages more broadly (e.g. antitrust law could be used to constrain/break-up a duopoly).
And while there are probably some services on AWS you can’t find at a competitor - that’s mostly a choice (aka profit margin) made by the competitor.
