Thing is even if you're not using Russian gas directly, prices are still going to be influenced by the global gas market (and the wider global economy in general).
Other oil has gone up so much because everyone is switching off Russian oil. Russian oil is not going up. So it's actually not a bad time to be a Russian oil consumer...
Anyway it's a very bad time to be a Russian oil consumer, because you'll be funding an unprovoked invasion and the countries that have sanctioned Russia may not want to deal with you.
An alternative view is that Russian oil and gas is not cheaper, but that it has extra costs which are not directly reflected on its official price. If you could put a number on the "moral cost" (funding an unprovoked invasion) and the "pariah risk" (other countries might not want to deal with you anymore if you buy Russian oil), and add that number to the official price of Russian oil and gas, there's a good chance that the result is exactly the price you get for non-Russian oil and gas on the global market.
Only in public media. Under the radar, they will still import Russian oil
