It's worth to add that Baikal Electronics is sanctioned by USA, EU, UK and banned to use ARM. So "feeling uncomfortable accepting the patch" is a nice euphemism in that case.
Well it's indeed one of major SoC suppliers for Russian military, but actually Baikal SoC are used for various civil purposes too: thin clients, servers, network routers, industrial automation/SCADA, CNC and so on.
These are subpar processors for the cost, they are only used when the certification requirements of the govt are in place. Ministry of defence subcontractors hardly count as civilian users.
