In most cases those companies are knockoffs of American companies and you've yet to mention cases were Europe is actually leading the way (aside from some unique cases it doesn't happen regularly)
P.s. Russia is not part of Europe, you can safely leave it out (and yes they've plenty of competitors to american companies telegram, Yandex, VK etc. we can't say the same for Europe)
Europeans simply do not see why they should try to "innovate" the American way: creating products that no one actually needs, and trying to get people to buy them anyway, often by killing the alternatives, which often results in more work, lower wages and higher prices for everyone. Europeans (other than AfD voters) would rather have a good enough society that stays good enough and doesn't decay.
You seem to know well what Europeans want but I bet you never got scammed by a taxi driver. Europeans like everybody want to simply pay less by having an open market that allows the best players to offer services without artificially inflating the price because that specific category some privilege.
If you claiming that Europe is not decaying probably you're living in the wrong Europe.
Europe is decaying faster than you think.
There are no companies that rise meteorically, capture billions of users and then collapse if they can't monetize. There are just companies that quietly provide products and services users want. If that's considered a failure to you, then... okay? Signal is American, but Telegram is Russian. And you can just, you know, send a text message, without involving any third party (but both your phone companies can see it).
Oh and the b2b companies... like ASML and SWIFT.
