Its ongoing invasion of and atrocities in Ukraine, mostly, but aside from that the authoritarian regime (and outlawing the free press) also doesn't exactly inspire confidence in Russian companies.

Hmm, might be the way Russia is effectively a dictatorship, the heavily enforced political censorship, or perhaps the major war they started against another independent European nation.

The attempted genocide of Ukraine, maybe? That seems to be #1 for most people right now.
