Sure, you can find examples of people who went into other areas, but given the very low barriers to entry (put some good stuff on Github repeatably, no industry requirement for an advanced or even undergraduate degree if you have talent, no unions or guilds, no competency certifications required to practice software engineering), I don't think there's such a big pent-up supply.
I'm sure there are a lot more people like me.
Furthermore, it's not like quantity supplied is perfectly responsive to price. It takes time for new people to enter the industry.
Talking about the long-term is rather pointless because technically, from a theoretical standpoint, everything is supposed to equilibriate over the long term. All shortages self-correct over the long term. Again, this is theoretical.
It's not an option for them to re-train, they don't work that way.
1. Companies in the Google/Apple/MS cabal
2. Other companies
Companies in 2 can always just pay more for what they want, since they're not governed by the cap. If they did that, of course, they could pull a bunch of people away from 1 and the price level would keep rising. That didn't happen because (mostly) only companies in 1 are able to pay at near the cap level anyway. So there might be inefficient hoarding, but it's just companies in 1 hoarding from each other.
It doesn't analogize exactly to, say, anti-gouging price caps for gasoline in a snowstorm (which, I agree, lead to terrible shortages and inefficient allocations), because this is equivalent to the gas stations setting a price floor (people shop at places with the lowest prices but work for the place with the highest wages). And then some gas station down the street opens a gas station with prices lower than the floor...
Said company would gladly go along since it benefits as well.

You can also see Microsoft in the screenshot of Google's "Do not call" list.
Not really, price ceilings have a well-known effect of causing shortages because purchasers who should have been priced out of the market use up some of the supply. If the price had been allowed to rise naturally, those willing to pay the higher price would get what they need.
