>Russia is highly centralized, so whoever operates in Russia has to not only abide by its laws, but actively collaborate with the regime.
You are saying this based on what? Do you have any relationship to Russia, have you visited it after the war started or you just read the newspapers?
Yes, there are some businesses receiving the direct calls from the government and I'm aware of several examples where they just tell "f. off" to a very senior official. Among the rest the level of cooperation or resistance varies from unstoppable patriotic propaganda and fundraising to CEO tipping employees about military recruiters during the mobilization campaign and relocating staff abroad. Russia is certainly not as centralized as you might think.
There is a tiny differenence between donating equipment to countries being invaded or under constant missile attacks (US) and actively invading a country with the stated official goal of exterminating local population (Russia)
