ARM Holdings is, ah, not necessarily the easiest company to work with. See the Qualcomm saga: https://www.theregister.com/2025/02/06/arm_qualcomm_nuvia/

The _current_ big EU supercomputer initiative does use ARM designs (https://www.theregister.com/2024/05/14/sipearl_rhea1_specs/ ), but you wouldn’t necessarily want to be totally dependent on them if you can help it.
