Oh, I’m sorry you had that experience. I had the original pixel, and the pixel 3a, and had both of them unlocked. Oneplus is also pretty good about unlocking their boot loaders without too much hassle. So that might be something you might also consider. If you’re interested in running lineage OS, just look at the official website to see what one plus devices are supported before purchasing. I currently have the OnePlus Nord N200 5G Unlocked running lineage OS 21
