AMD vs. Intel is a great analogy, really (there was Cyrix and others, as well). Try to understand it. And in the end, both have benefited from it; AMD has reproduced the Intel's interface, and later, Intel has reproduced the AMD's interface (AMD64) when it worked out better.

Not a good analogy. Intel and AMD had a very profound and comprehensive second source agreement for a wide variety of Intel designs, eproms, 8086, 80286, '386, 8051 and more. Intel provided AMD with full mask tapeouts. In the 1970's the idea was that customers, (especially the military) of chip company’s would be very reluctant to adopt a design unless it could be source from multiple fabs.
Intel was not the behemoth it is today. It started out making small DRAMS to replace core memory in mainframes. The first DRAM was intel's 1103. Then IBM adopted the 8088 and Intel became a processor focused company. By the mid 1980's Intel was fed up with handing masks to AMD and wanted out of the contract pre-maturely. AMD was still able to make 386's from intel masks but that was the last in the second source agreement. Lawsuits were launched and I think they were settled out of court.
As far as I know GigaDev never had such an intimate business arrangement with ST.
dgtl:
Yeah... F03x and F07x in smaller packages were gone from all suppliers. Had to redesign multiple boards to larger package to get manufacturing going again. Not nice at all.

We were finally able to secure enough of an ST MCU in the same family for the next few months.
Still likely switching over to NXP since someone was saying they are a more reliable supply. (Let me know if you don't agree with this) After a few months we have no idea what our volumes will be so if ST MCUs are still at a 30 WK LT then we are in a bad place.
I've already started porting our code to NXP and so far it is a good experience, toolchain is very similar to ST.
EDIT: Also, anyone going to short STM? It's at an all time high and I'm betting a ton of companies will switch over to someone else because of this.
Kjelt:
ST vs GD : ST pays hefty fees for use of the Arm Cortex core design, does GD too or did they copy paste that as well :-//

Interesting info about this shortage. Looks like not all the stm32 are affected equally by this shortage or maybe demand is lower for some families.
