They just posted their first net user loss - so maybe not "in droves" but their username is certainly declining and will continue to do so without drastic change

He's a bad guy and invading Ukraine is horrible, all the usual caveats. But Putin under every rock and behind every bush being responsible for every toothache and hangnail is getting old.

You can't make any claims about Facebook's position based on a single quarter's result.
Especially given we are in the most tumultuous period in the last few decades.
The 90s covered the fall and breakup of one of two world powers, and had a gulf war and the breakup/war in Yugoslavia, so that's similarly rules out.
The 00s covered terrorist attacks on the Twin Towers, the Pentagon, and London, changing air travel worldwide, starting wars and inspiring more terrorism (Madrid, Mumbay). Oh, and a financial meltdown compared to the Great Depression. So that's probably also not in your "last few decades".
That leaves the 2010s, which cover (amongst others) the start of the corona pandemic. I guess you're including that event in your "recent decades".
Plenty omitted from the above, such as famines and wars in Africa, news from Latin-America, "where's my vote" in Iran, the Arab Spring, Rohinga & Myanmar, ...; in short: we've been in a couple of tumultuous decades for a while now.
