> How should the memory companies have acted differently?

Same way nVidia did through the crypto insanity - make sure they're supplying enough to the consumer market so it doesn't get completely destroyed and pulls down the other parts of the consumer market they're reliant for long term success.

> Should we blame this on memory companies or the AI companies bidding for memory?

Blame doesn't change the outcomes, neither does it improve the negative consequences. Think in terms of "what does destruction of our consumer market mean for my prosperity?" not "oh, how do defend poor companies again?"
