See, the logic behind this is asinine. Their excuse is to not participate or allow Russia to participate in a shared economy.

But preventing Russians from spending money in a foreign economy doesn't harm them any. It helps them.

To actually harm the Russian economy you have to do the opposite and not BUY from the Russian economy.

The former enables Russia to hold onto capital. The latter drains them of capital. Especially if the Russians can still buy from non russian companies, but none of their own stuff is being bought.
