Here's where you're wrong: Yandex is not just a search engine, it's the fifth largest search engine in the world(!) and is also an email provider, a social network service, a payment service provider, a smart assistant, a ride sharing service, a cloud provider, a ML/AI and autonomous vehicle researcher, a V.C. fund. Basically most if not all of what Google/FAANG is doing.

Which European company does all those things and at such a large scale? Having some random small search engines that nobody is using, funded and kept alive by EU grants just to show that "we can", is in no way comparable to the scale of Yandex.
