I dunno if I’d even consider them an industry leader, unless you break down their ubiquity by industry category (in which they lead graphic design and maybe video editing, iirc). They lead phone sales in the US by a lot, but their overall desktop share is still relatively small (<10%), and their global footprint is buoyed only by iOS (which is still below Windows and Android).

I would say they’re an innovator, and they push certain companies to innovate, but they don’t really lead by that many metrics.
