Considering, just for example, the sort of grilling government politicians get from Jeremy Paxman and the sterling exposés done by Panorama over the years, the answer to your first question is kind of obvious.Why is RT almost always described at "Kremlin backed" while the BBC is not described as "House of Commons-backed" or government backed?
It is well known that working at the BBC has provided cover for UK intelligence agency assets in the past.
For that matter, RTE should also always be described as Dail-backed, or government-backed (with a threat of imprisonment facing citizens that do not comply with government orders to support the propaganda outlet financially deserving a mention too).
All that aside, what about freedom of speech and expression? It seems Europe's commitment to it is as weak as ever...
RTE's tradition isn't quite as proudly independent but they can and do challenge government policies and their outcomes.
