Maybe so, and who should be surprised?
Recall the Turkish disregard for Greek Sovereignty, Islands, Borders, Waters and Airspace since 1950. The US, NATO and Grece have done nothing, and the violations must be near a million now.
Yes Russia should bring Turkey to heel, and get stabbed in the back by the US, NATO, UN and EU and labeled an Illegal Aggressor Nation, by those nations illegally present in Syria.
It's so obviously a trap it's laughable.
If the US wants the airspace closed to Turkey the US can do it in eight hours by simply shooting down anything that Erdogan flies there, and prosecuting the pilots for War Crimes.
The US is the most responsible for this tragedy, and Russia is the least.

I agree 100%. Get the US out of Syria.
