Worked for me.
The news settings have been off after install & new tab gave me News + silly ads.
If Opera news could be configured simply, like no Fox news, no Breitbart news, no Sports then I might leave it on. I like to know news as it happens. I check DemocracyNow.org daily for headlines, and have Google's weak-sauce News open all the time.
