Yeah - I used to only buy phones with an unlockable bootloader. But I found that I didn't actually ever install open source firmware (I have, but I don't trust the security).
Aside: the Android 9 security update feature is Project Treble. However apparently it doesn't make that much difference for many brands/networks because Google doesn't control the updates directly: https://www.computerworld.com/article/3306443/what-is-projec...
However, my Nokia has been getting security updates quickly enough for me. And I love dual SIM when travelling.
