Huawei is more likely to do a poor job of keeping said data to itself, either intentionally (selling it outright) or by getting hacked.

I'm convinced Google wouldn't sell my data - it is immensely more valuable to them if they're the only ones with it. That said, they'd still use it - to target and profile me, and of course I expect them both to share it with the respective governments.

Moreover, if I use Google services through a Huawei phone, they both end up with my data, while if I use a google device at least it's just Google. I'm not enthusiastic about either, but, hey, lesser of two evils.

(For the record I have an iPhone and try to avoid giving Google too much data about me)
