Yes, and since they didn't had to pay it anymore there was no reason to not have an Anatolian state as a counterweight to the red behemoth, except the Turks, f*ck those guys.But the Western Entente had tacitly accepted Russian ambitions before the Tsarist government collapsed, IIRC.
The collapse just let them avoid paying the price they'd expected to pay.
The ideal move for the Ottoman Empire during WW1 is not to play. That being said the Entente fully were thinking the sultan would rule as some kind of proxy of a non- Empire from internationalized Constantinople. The turkish nationalist insurgency came as a surprise.
