Lol, Europeans are quick to adopt all the worst things from America related to tech, including social media, streaming services, proprietary software, iPhones, and random IoT garbage.
Every European you meet on social media is necessarily the subset of Europeans who adopted social media. A subset of the population adopting a subset of the stuff doesn't mean adoption in general is as universal as you might assume.
e.g. podcast I was listening to the other day had a German complaining about their bank, after the bank suggested they send a fax.
