I think "upstarts" is being used uphthread to mean "startups" and "giants" is being used in a general, not market-specific, sense; that is, it isn't referring to entities that are mere new entrants in a particular market but still potentially quite large and established firms displacing incumbents in the particular market, but new, small-starting firms taking over a newly-opened market segment, beating out the large, established firms (from other markets) that are also trying to compete in it.
