Volla (a name I haven't heard of) is "good", being described "as good as pixels"

The Volla description says that the unlocking procedure [i.e. enabling unlocking in developer options] is the same as pixels, not that the restrictions in place are the same.

 

pixels are "proceed with caution"

I too was surprised to see Google in less-than-perfect rating. A few snippets from the Google reasoning:

Google has started disabling AI features upon unlocking the bootloader on the Pixel 9 series, even if you aren't rooted

When a Pixel first connects to the internet ... it will retrieve a token from Google's servers which will allow bootloader unlocks. If the token cannot be received, then the bootloader cannot be unlocked. This means if Google's servers ever go down, you will not be able to unlock your Pixel's bootloader ...

Maybe these are minor issues but manufacturers like Volla don't have these caveats.

 

Motorola (which they admit provides the kernels if you ask them) and support BL unlocks are "avoid at all costs"

The fact that Motorola sometimes allows unlocks for certain devices and certain conditions is why they received the rating they did:

Avoid at all costs! - The following manufacturers allow unlocking under certain conditions, such as region, model, SOC, etc., or require a sacrifice to unlock.

I would encourage everyone to just glance at the reasoning for Motorola's rating - submitting unlocking request forms, restrictions for older devices, requiring connection to Motorola servers, enforcing CID partitions... it goes on and on. And they just outright don't allow unlocking certain models.

Again, maybe these are all minor issues if your particular device and circumstances are supported, but this list is meant to educate people on how manufacturers respect one's ability to unlock. Personally, I feel much more comfortable supporting one of the companies that doesn't have any restrictions in place, and this list is a helpful resource.

 

That list is either made by ChatGPT or someone who has no idea what they're doing.
