Remember the "chip shortage" all throughout the pandemic? It's not like the whole world switched to a Soviet style command economy between 2020 and 2022 yet we still had it.
If you were willing to pay more than the market rate, there was no problem in finding chips.
ChatGPT mentions some factors for why suppliers didn't just raise prices until the demand met the supply:
1. The industry often has long term contracts that fixes prices months or years in advance.
2. Even without such contracts, the value of stable, long-term relationships with major customers made suppliers keep prices stable.
3. Governments intervened to prevent "price gouging" for favored industries, and even without such intervention, perceived price gouging can be more damaging long term than is made up for by near term profits.
So you're right that there was a real shortage for a time.
But note my original caveat: "On a market with free pricing". Unfree pricing (contracts/regulation) was one factor.
But PR considerations, which I admit I didn't think of, was also a factor. So I learned something here!
Instead prices go up or down until supply and demand meet.
So talking about "shortages" in this context doesn't really make sense to me. Yet that's the terminology in this field, and the resulting confusion is unavoidable.
