Weird how LineageOS supports ~300 devices while still managing to release patches.

I bet this CVE's patched quicker on a samsung device running LineageOS than the stock OS.

The real difference is that Google has a more competent software development process and release process than other android OEMs, regardless of how many different devices they have.

LineageOS doesn't customize the hell out of their OSes per device.

That's core of the issue. Samsung takes Android, customizes per device and then tosses them into the world. So now they don't have 1 OS to update, they have 100s of OSes to update.
