There is no absolute right of free speech in the EU (and probably most countries); foreign companies operating there are subject to local laws when doing so. (In my non-EU country that tweet could be interpreted as a hate crime too, quite uncontroversially)

Sure, but is this joke actually illegal?

I'm not as familiar with EU laws, but if I posted this joke online in the UK, then yes, it could easily be considered "grossly offensive" and therefore would be illegal.

I won't say it happens particularly often, but we do charge people in the UK for posting offensive jokes. Hell, you can be charged for saying something factually true if it's offensive in the UK.
