It turned out that they are mostly a Ukrainian company, and when the war started the CEO decided to terminate “services to users registered in Russia” with only four work days notice.
I don’t know if any customer account was actually suspended. I also don’t know what “registered in Russia” means, is it nationality, residency, billing address, customer’s IP address or the A record. Some EU clients also received this letter.
I can relate emotionally. But this way to address existing customers, which have paid for their services, is whimsy and unprofessional. I also think that discrimination based on region or nationality is unnecessary broad. It certainly didn’t stop Putin.
Just to be clear, I believe Ukraine needs and deserves all kind of support to win this war.
