BBC is just way way better at it, way more subtle, having been doing this for 100 years. When push comes to shove they toe the line just like Russian or Chinese media. RT just doesn't have the same funding or talent to make stories more sophisticated. Obviously, the gov must hide any links to BBC to maintain the appearance of free press. But I'm sure pressure is exerted one way or the other, for example:
> From the late 1930s until the end of the Cold War, MI5 had an officer at the BBC vetting editorial applicants.
Looking at how UK and EU now outright banned Russian TV and media, I think it would go unnoticed if they started removing or just not hiring certain inconvenient journalists. Certain thoughts are just forbidden these days; it's career suicide to even doubt the gov line, just like during covid when it was practically forbidden to question gov measures or vaccines.
