I don't think that is right. You don't decide to be a criminal, you decide to perform an action, you get labelled then by others.
Some people want to destroy big businesses, they can possibly make as much money as they need already.
Of course you can make money through a side-channel that's less traceable too.
Note that it could make sense to a pro-Russia Ukranian group to extort money abroad and to hurt economically on the target. That seems to be the Russian MO to not be directly implicated in the Ukrainian operations: help with tools, weapons and money the groups that are already in place.
They give up direct control over the actions in exchange of deniability.
So it was targeted at the Ukraine, but plenty of multinational companies also operate there, so they were collateral damage
So, even if in the infosec world you can never say never, but just as Stuxnet is generally attributed to Israel/USA, in the same way NotPetya is attributed to Russia, even though none of these countries will ever admit they actually did it.
