JacksWendel Is the google bootloader opensource?
I don't believe so.
JacksWendel I would preffer a bootloader coming from grapheneos.
Sure, me too, but that's not really possible at present. Perhaps the Motorola partnership will include GrapheneOS review of some components that are typically closed-source, but perhaps not. We'll have to wait and see (and in the meantime questions on the forum won't reduce the waiting time: we'll have to wait and see).
JacksWendel Btw does grapheneos modify the kernel or recovery, or is it just the OS?
GrapheneOS modifies both the kernel and Recovery. This is why there isn't a GSI release (source). Users who are interested in what GrapheneOS does/doesn't do may benefit from reading the material on the web site, including the FAQ and the usage guide.
JacksWendel Googles dont be evil must have been the worst joke in human history, that aside if the bootloader isnt opensource how could anyone ever trust that google isn't spying?
It is possible to analyze binaries without source code! Security experts do reverse-engineer closed-source components. There has even been some reporting on the Titan M2 firmware.
Also, if "spying" involves transmitting information to Google, the information must be sent on a network, and people (including security experts) monitor networks for unexplained traffic.
That said, if a fear of Google is one's most-firmly-held position on computer security, at present many people believe that the main competitor with GrapheneOS in terms of security, on generally-available devices, is Apple, which is very firmly closed-source.
