>Didn't Russia quickly spin up an alternative smartcard payment system

The MIR payment system started functioning in 2015, long before Visa/Mastercard pulled out of Russia

>Android app store

Initially there was some fragmentation because several companies raced to develop "Russia's #1 answer to Google Play Store" but everyone eventually settled on RuStore developed by VK (Russia's Facebook).

Generally, Russia already had replacements for most major American services long before 2022, and with better market penetration: Google => Yandex, Meta => VK, Uber => Yandex Taxi, Amazon/eBay/Craigslist => Ozon/Avito/Wildberries, etc. Lack of own app store was more like an oversight. Europe is at least 20 years late in the game.
