Possibly anti-Russian bias? It's common here. That said, Taxify is pretty good and cheap, and personally I don't bother with anything else.

I live and work in Tallinn as a remote worker for a few clients; internet is cheap and fast. I've half-Australian / half-Estonian, and have Estonian citizenship so I'm not really familiar with the e-Residency program except to the extent that it's clear the government is investing a lot into it.
