Since nobody else has mentioned it... "vulnerable to hacking" is doing a lot of heavy lifting here. It's "vulnerable" about as much as my LUKS desktop system is vulnerable.

These charts have been available for years and don't tell us anything particularly scary IMO.

This "hacking" especially for BFU/turned-off Pixel devices, at best would amount to brute-forcing your password, either on-device or after copying the flash elsewhere.

Short of using top-secret multi-million dollar 0days or something, there is no inherent Pixel flaw that lets them bypass the device's encryption or anything crazy like people are thinking. They still have to get your password somehow, just like anyone else.
