It's not only the design of the hardware, but also patches for vulnerabilities and delivering updates for several years.
You're suggesting it's ideological (which is completely untrue), while the fact is: pixels are at the very moment the only Android hardware secure enough to even care about hardening: https://grapheneos.org/faq#future-devices
(there's little sense in securing the OS if the hardware doesn't allow disconnecting the USB or there is no secure element throttling PIN attempts, right?)
