Duolingo is a for-profit company, that is their job

They do not have any profit in « that market » because app is demonetized in Russia and Belorussia though

Wait...90% of Hexbear isn't gay?

The way I see it is that Signal's primary ""mission"" is to provide secure, private communication. Chat control presumably would mean they could not fulfill their mission, so they should rather pull out.

For Duolingo, their mission to provide easy access language learning is not directly impacted by the rules in Russia. Even if all the employees are against the rules in Russia, Duolingo can still provide language learning in Russia, which they might see as a worthwhile endeavour.

After all, afaik Duolingo being available is not actually beneficial for the Russian government, as it's another way for money to leave Russia ( ? I think), and makes it easier for Russians to get a wider worldview.

Money makes cowards

As per their ceo, they want to provide access to education to all (which is good since educated people are less likely to believe propaganda) and they do not monetize the app in that country in any way, which means no taxes going to putins pocket.

People are quick to jump to conclusions but they’re right here.

Most multinational web apps will have different deployments for different countries.
Locating the servers geographically closer to the users reduces latencies and costs.
Running different deployments allow them to tailor more closely to local regulations, without having it impact everyone else
