It looks interesting to me. It am kinda skeptical about it, most of the small chips which are under shortage are small chips, and definitely not made with latest 5nm/7nm node sizes. Most of this chips can easily manage to fall at 22nm node size, where TSMC is no monopoly.

I think its just a PR stunt by TSMC, to overprice and prebook their production capacity for increased margins.

PS: It is my personal opinion.
