Probably just trying to avoid Russia's high overflight and ATC charges.

Bingo. This is almost certainly the one and only reason

The Russian authorities do not allow wetleased airlines over Russian airspace.

Probably one way of reducing competition with their own airlines.
You may recall a few years ago when Russia banned AC from overflying Russia on it's then new seasonal YYZ-DEL nonstop service. The reported reason was that SU had been carrying a lot of Canada-India traffic and they wanted to make life as difficult as possible for AC.
However, Canada quickly retaliated by banning Russian aircraft from Canadian airspace (except for limited scheduled services to Toronto) which had a major impact on SU services to the U.S. After Canada imposed that ban an agreement was quickly reached within the next couple of weeks and the overflight bans were lifted.
