Expose to what exactly? Sanctions, neural-gas attacks or nuclear weapons? Does Russia have any legal or technical levers which could potentially harm Fastmail business?
I mean, I legitimately wouldn't be surprised if they took political prisoners if Fastmail showed up to court to fight, or hammer out an agreement. Let alone what they would end up having to submit to while operating within the country. Russia is known to be pretty hostile towards the west.
