My reasons of cancellation are less fiduciary and more of a policy. In 2022, IEEE published an interview of two Russian researchers and effect of the intellectual & economic blockade in Russian academia after Ukraine invasion started. It sought pleas for donation & help. Many people pointed out it was tone deaf since the ones really suffering were the Ukrainian academics who were dislocated or persecuted in their own land. IEEE never commented or retracted those interviews & several people canceled their membership in disgust.
I subscribe to Spectrum for about $50 through Omeda rather than continue giving IEEE additional membership fee. I know some part will be shared with IEEE, but I am minimizing this by conscious choice.
