There hasn’t been any monetization since shortly after the invasion started. If I have to guess, Google was just footing the bills so they don’t lose presence to some local player when it’s all over.
I’m actually more curious as to who finally pulled the plug, Google, or the Russian government; and why finally now. Article made it seem like the Russian govt wanted to violate net neutrality and slow down YT’s traffic, but makes no mentioning of which party ultimately took the service down.
