Ok, so go to the Pinephone battery spec (everything is publicly available) and point me to where it says the in-battery protection circuit protects the under/overtemperature condition.

In fact it's just the common protection circuit that just cares about over/under voltage and over-current conditions (mostly just a short, because the cuttoff current limit is 6-8A and battery's max recommended sustained current is 1.4A). So you can overload the battery 3-4x for however long you want, and that circuit will do nothing.

I am not aware of any case of fire. So unless it caused such a bad fire, that everybody involved died, I think I would know about it having followed the PinePhone very closely, especially since June for my blog.

That said, as the fix seems to be rather trivial, distributions should just check and ship a new kernel if necessary.

I don't get this criticism. Doesn't it make sense to raise the alarm before the fire happens?

Yes, there were cases of Pinephone burning people's fingers, due to modem being used as a heatsink, and distros not doing any testing about thermal regulation working. You can easily get the modem to heat up to 70-80 deg C in that case. With regulation on, it would not get over 60, which while not pleasant is not at least hurtful.

Move fast and break things !

I recall once a co worker said they'd never use Android again since it froze when trying to call 911.

Gives Apple more ammo in their fight against Epic, users expect their phones to work , which Apple can't guarantee if anyone can run whatever binary they find.
