How much of Huawei's research is done in EU? They have at least three research facilities in Sweden alone. Ericsson does a lot of research in the US. All of these companies are global, so to assign their research to only the country where they're headquartered gets a bit nonsensical.

Huawei’s tech is better per $ because they skipped years of R&D that they didn’t have to price in. I remember when their products included Cisco manuals.

It is cheaper since the chinede spy agencies sponsor it.

If you knew that important people would use your phones you could as well give them for free - easier to spy on them.
