This is quite unprofessional of them. Unless the jurisdiction specifically forbids it, taking sides like this and kicking out their paying customers with little notice is nothing but opportune posturing that reeks of deplatforming. Don't take out your grievances on already subjugated population.
This isn't a business or political issue for them. See the response from the CEO in this discussion. They have employees on the ground in Ukraine who's lives are in danger right now. Given that, I understand why they are not that concerned about the fairness of it.
It's hard to hold the complexity of these situations at the best of times, and when people are feeling stressed, afraid, and so on, capacity for that plummets further. Then we start feeling like empathy for the suffering of one person or group means demanding suffering for others.
