This particular article is most likely fake news based on rumors from "journalist Amir Tsarfati" because if they were to cut it off they would definitely do it at the passport control, not "Russian airlines sales". There are tons of non-Russian airlines flying out of the country, including half a dozen Turkish ones, Emirates, etc. They already flag people dodging debt and child support at passport control, they would do the same for the draft dodgers, but so far there have been no reports of that happening.
