Why is that interesting? Are we expecting another global semiconductor supply chain problem?

Because people who _needed_ to buy a Raspberry Pi simply weren't able to do so.

Exactly the same as every other hardware supplier. For pi there was some kind of scheme for businesses who _actually_ needed the hardware in order to stay in business. No idea how that worked.

Either way, this is all history. Raspberry Pi boards do not cost hundreds of dollars as claimed.
