Doesn't look like a bad idea from the Kremlin's view. $2.52 a gallon for gas is still an outrageously high price for the huge majority of Russians. That's the equivalent to gas costing ~$32 a gallon in the US, using the old PPP purchasing-power parity numbers for 2005.
Plus, as the link shows, it's wealthy Europeans who will mostly be supplementing this policy.
This is just another move in the pipeline deals that Russia has been fighting for the last 15 years. Bits and pieces have been documented on FR over the years.
