That’s a surprise regarding RT as they operate in several EU countries.
We get our own feed of RT with UK specific news programming, which as a technically separate service requires it's own separate license. Therefore RT have to either start uplinking the Pan-European feed for Ireland, or get a license for the UK service.
Sky require broadcasters to send them their licenses for both the UK and Ireland to secure
EPG carriage in the respective territories, so either RT haven't yet got around to providing their license to Sky, or for whatever reason they've not bothered to get a new license (yet).
Some of those Global stations that have been removed are on DAB in Malta.
Really?? Which ones exactly? And how on Earth do the signal of the Global stations even reaches Malta?
I suspect the Global station carried in Malta aren't officially sanctioned by Global, but are rather being rebroadcast by the local DAB multiplex operator. I don't know but it may be that Maltese law allows this, much in the same way Swiss law allows their TV platform operators to rebroadcast any channel that can be received in the country.
It's very likely they're rebroadcasting the online stream or picking it up from the Astra (Sky) satellite. With a big enough dish Malta is just in coverage of the Pan-European beam, which I believe both the Sky/Freesat feeds of the individual stations and the UK DAB mux distribution feeds are on.
