I can't find the link, but a couple days ago, they said in a thread here it was due to their lack of support of some important security features, and remarked that it didn't look like they were even interested in supporting them.

You cant re-lock the bootloader with a custom key which grapheneos considers a cornerstone of their security model.

Yeah, otherwise the bad guys can just wait till you're not looking at your phone, reflash your it with a backdoored version, and wait for you to unlock it (evil maid attack).

The bad guys e.g. the police detaining you during a protest and temporarily seizing your property, or the border police "scanning" your phone.

		If your phone was in hands of police you better sell it anyway because they could install a physical GPS tracker, etc. So locked bootloader doesn't change much. Also if you live in a truly democratic country you don't even need to set the PIN code - your rights are protected by the law.
