You took some very "fresh" parts in the absolute hottest and the most critical part of the industry and you wonder were are the detailed datasheets and nice application notes from which you can design your projects ?
Well I have some bad news, soon there will be no more whining about ginormous amount of documentation that one need to read and understand to be fully capable of use a specific chip/MCU/whatever, because there will be no more of this stuff, once gone will stay gone for ever. And no, you will not be able to vote with your wallet, maybe for a short time until everybody synchronizes and the "obsolete" parts with their abundant docs will become EOL.
A ultra-simplified data-sheet, a demo board with some software for evaluation, a super patched Yocto for Linux running MCU and that's it ("...we comply with Open Source licenses as little as legally possible, please use our supported binary firmware image...". And hey, if someone still use those Borscht sensors, a fully opaque "AI" to calibrate them will be available, an that's it, basta.
So what about designing my own products, you may ask ?!?
Well, enters the "XXX Company Engineering Services", you give them the specifications, pay and get a nice Chinese design, also for the continued revenue stream you'll also get support contract. No, access protocols are proprietary and only available via our "IoT Cloud Services", for a moderate monthly fee/device, you get the latest software updates and bug-fixes. You'll only have a say in the branding of the unit and the shape of the PCB, maybe.
It may sound, bleak, paranoid or far fetched, but this is the global trend, the time of small/medium design houses with their little niches, JIT supply and "I design it here, produce it in China and slap 10000% price on it" are all gone and the consolidation will happen fast. Now you can see them (including here) twerking like the suffocating fish out of water, desperately scrambling for the bottom of the barrel parts and waiting for good old times of unlimited availability, easy full BOM ordering and fast delivery to come back, any time soon, the "hoarders will be punished and sell their stock for pennies on dollars...".
Is really sad and pathetic what is happening, this the world now and we're joining the watch makers and other dinosaurian jobs, some extra/ultra specialized design houses may survive, but most will be just gone or be assimilated.
Cheers and have a nice Easter celebration for those who does it,
