Don't be silly; this is not anyone hiding anything. If a website survives based on advertising and needs to now pay a service to keep them up to date with the latest EU regs, then they may just switch on GeoIP filtering and be done with it.
And I'm sure it's just a happy coincidence that news about US military murdering civilians cant be accessed outside of the US :)
"In the EU" and "outside the US" are not synonyms.
If its of any import, european outlets are welcome to write their own reports.
Probably just has to do with not being worth the hassle to comply with European regulations. If you only have a little European traffic, it's easier/cheaper just to block the EU.
This is almost 100% GDPR and laziness around their legal liability. You can find this issue of not being available in the EU for many sites entirely, regardless of if the news is about the US or not.
