I can access RT.COM just fine from A&A, no certificate error. The cert shows as issued by R3 and is accepted by Chrome. A&A have had to stop returning RT.COM via their DNS servers due to government demands, but I'm using my own, or it should still work from other public DNS servers like 8.8.8.8.
So when countries like Russia ban foreign media news sites they are criticised for it and accused of censorship and pushing their own state media and propaganda onto their people. So when the UK does it, is that not the exact same thing?
I find RT.COM is more neutral and factual and covers important world news I can quickly get to rather than the BBC News site which is more like a Take-a-break mag these days and full of click bate articles.
