These last two, at least, are just lazy press release reporting. That's not a problem limited to the BBC, of course. The 24 hour media cycle, which in principle should lead to a more informed citizenry, has instead led to those in power having greater influence through the provision of the content necessary to fill the cycle.
I don't think the notion that big stories get killed because they upset the power brokers with the funding is at all controversial. See: Wigand, Jeffrey. The unusual thing about that one was that it eventually came out.
