This is just Crypviser spreading lies. No, being on that Russian register doesn't imply any intention to comply with any wiretapping / censorship requests; in fact, IIRC, it doesn't even necessarily imply any consent to being added to the register. Saying that Treema's being added to the register means it "moved under the control of the Russian government" is no different than adding their company name and address to some Excel file on your computer and then saying that Threema has moved under your control.
