At this point, there are 5000+ dead Ukrainian civilians. If at this point you are more concerned about Russian citizens buying domains names from one vendor than you are about Ukrainian civilians getting blown up, that's in no way a neutral position. Similarly, you and Namecheap both have freedom of association. Their using it to enhance sanctions against Russia is exactly as political as you using it to boycott them for their choice.
Are there any exceptions?
Yes, we continue to provide services to:
all anti-war media, protest resources and any type of websites that are helping to end this war and regime;
Russian citizens who are not Russian residents and don't support this regime in any way;
independent journalism;
non-profit organizations.
But I guess people who support Russia's genocidal attack on Ukraine are still going to be salty.
