I think Google is something that Russia doesn't really need, except for Android, as many people are using phones powered by this system there. Otherwise, Yandex has everything they need, literally.
Imagine if there was no Google in the UK, but instead, a dedicated search engine with all the essential services, even robots delivering food, all fully localized - plus an in-browser AI assistant with a voice like Annie Warburton's that speaks, jokes, tells stories, makes recommendations, and helps you find things on the internet - and understands regional dialects. That's how Yandex Alice works.
Essentially, you could ask for things like 'Who sells the best mash and bangers with army and navy around here?' ...lol, and it would know that you mean mashed potatoes, sausages, and gravy in your nearby stores like Tesco or Sainsbury's.
Locals here would simply never need Google, unless some needed to search for something very specific in other countries like France, Italy, Germany, Spain, etc., as Google could have more info about that.
Check this vid out - Russia has over 16,000 sanctions. Most countries with this amount would stop existing, but they thrive. So i think, if G pulls out of the country, that won't matter much to Russia, even improve local services.
