It might be not quite so bad, as there are pin for pin swaps on quite a few of the chips, but I can't find an alternative for the 600 series programmable gain chips that are used in VCA designs. Sadly when this type of thing happens, the warning of end of life tends to produce big price increases, as they see a benefit in clearing their stock quickly to panic buyers.
The problem is actually not just in high end audio - it's used in large numbers of designs that use digitally controlled input stages, like microphone preamplifiers, scientific instrumentation amplifiers, audio Mixers Consoles, PC audio interfaces, digital video cameras, digital audio snakes and portable audio recorders - essentially devices that have audio passing through that needs level adjustment.
Your video title - the end of VCA compressors is the tip of an iceberg - this seems a very strange business decision for That - I suppose something impacting high end gear means not a huge number of sales, but it seems all these chips are way more prolific, and are in the analogue circuits of quite common gear?
Still - the Chinese factories might well be able to gear up for continued production. Their semi-conductor plants are really quick at picking up on potential sales?
I fear your list of gear impacted is much bigger - common audio ICs being unavailable is going to be quite impactful?
