Unless a species has a really, really unique call or song, I've made it my personal rule to get eyes on it and, if I'm still not convinced, to take a picture and cross reference with iNaturalist and what folks on there think of it.
I've learned to curse the species that differ from others by the sheen of the backs of the males' necks or the angle of a wingbar. Also, gulls that only differ by things like the color of their feet or beaks.
I would assume that re-targeting a design to a different fab's process would change enough about it that you might as well just do verification in simulation rather than sidetrack through Fab2.
Of course, we don't yet know the specifics of this particular case, but I'm willing to lean towards the people receiving legal letters threatening CFAA action until there's more information.
I've been curious for a while about the overall taxonomy of security, especially for embedded platforms. It seems like the only hope is defense in depth, given the power glitching attacks and the like that you can find demonstrated.
Specific to the Raspberry Pi, I believe I even saw a thread at some point where one of their firmware engineers was making the case that secure boot on the Pi 5 was equivalent to a TPM in almost any reasonable threat model, since, in either case, you were out of luck if an attacker had physical access and was willing to put in enough effort.
If you're trying to build a couple of units of some embedded thing where you need to toggle some GPIOs or serial devices in response to requests over the network, but don't have the expertise or resources to do it with a microcontroller, a Pi is a great option - you know you'll have software support, and you know that the vendor will be making the exact thing you bought for 5-10y.
For hobbyist stuff at home, I agree, though. A mini PC is probably better for homelab stuff, and an RP2350 or ESP32 is probably better for anything embedded or battery powered that you want to do.
I've spent far too much time messing around trying to get TPMs working over SPI or I2C to meet security requirements with 4Bs and 5s over the years.
I did have the same feeling about flashlights for camping/hiking with lithium batteries, though, until someone walked me through just how much better they are than lugging around AAs.
USB-C has allowed me to grab one decent two-port charging brick, two solid 6ft cables, and charge just about everything I own just by keeping those in my backpack. If I think I'll need to move any data fast, etc., I just throw my one good USB4 cable in my bag, too.
I will admit, though, that I've had some crappy situations at work where it turned out my flaky monitor setup was due to the stupid work-provided docks coming with cables that only supported 10Gbps. Better labeling would've solved those ones.
And if your landlord is balking at including heat in rent, there's a decent chance it's because your bill will be outrageous because there's zero insulation, and as a tenant there's little you can do to fix that.
Entirely unsurprised that someone would refuse to give up their workflow, though! I've rarely found a user with specific needs who wants to change literally anything else about their system, since what they have works for them.
The language towards the end of the press release implies to me that they're targeting last-gen Intel MacBook Air users thinking about upgrades more than anyone with an M2/3/4 MacBook.
Typically seems like $100-200 per year for coverage that would handle the loss of most of one's possessions, provided you don't get screwed by "well, you don't have the receipt" or "we only cover water ingress, not floods or leaks".
People seem to be pretty universally incapable of not assuming computer products to be infallible, especially when they might get some extra money in "over occupancy" fees.
