Eh, f*ck you. Free software it's for any purpose. The more tech alternatives we have, the better. Elbrus, RISC-V, Loongson... we need heterogeneous environments to avoid attacks.
Signalling is important. That's why certain licenses exist even if they're trivialy circumvented
It would be free even if they intentionally and maliciously refactored the code just to make future backports harder.
Honestly both stances are easily defensible here, but if Elbrus was a development drag this would be the perfect moment to reevaluate support.
