This seems like the most cynical take possible, most of those choke points aren't really that firm anymore. Microsoft had a brief chokehold and then smartphones became the computer of the working class. Google is dominant in search but now they're competing against other megacorps who are investing heavily in catching up. All that's died is the naivety of the 80s and 90s that believed small mom and pops would somehow be outcompeting megacorps rather than serving as product development for them.
