Open Telekom Cloud was at least in 2020 running fully on Huawei Software and hardware: https://www.open-telekom-cloud.com/de/blog/vorteile/die-sich...

Deutsche Telekom used Huaweis OpenStack implementation.

I haven't found any information that this changed, so I assume it is still running completely on Huawei. At least they made sure that they still get chips from the US despite sanctions. ;-)

Telcos fell in love with OpenStack some years ago and went all in. Biggest problem with OpenStack was you needed a lot of hardware to learn how to use it and the talent pool was quite small.
