And the logic is?

Simon Heffer in the Telegraph has a typical Telegraph rant at the BBC, picking out a few instances in a report that reportedly (I haven't read it) clears the Beeb of systematic liberal bias.

Heffer angrily rejects these findings on the grounds that he has met many people who have worked at the Beeb and tell him that

a prevailing wind of Leftism blew strongly, and, if they wished to remain in productive work, they knew it was best to sail with it.

Of course Heffer comes across a wide cross-section of right-wingers. His answer, of course, is to privatise the BBC.
