Given the context of this thread and the current war, I think it's pretty clear Namecheap is turning away customers in Russia's jurisdiction because they don't want to support the Russian regime through taxes. The fact that the people who live under that regime are mostly Russians is tangential.
It's just like how Walmart.com doesn't ship to China. That's legal. And if I'm in the US, and I put a Chinese address on my Walmart.com account, and they don't ship me a package, that's not discrimination, that's just a mistake.
Now, if Namecheap starts intentionally going after people of Russian origin outside of Russia, that's a different story, but it doesn't look like that's what's happening here.
