As aforementioned elsewhere by Spokey, its been a long time since the Beeb were a consistent purveyor of quality output. Sure, they may pull the off blinder now and again, but that isn't good enough when some of the capitalist outfits are putting out consistently high quality content. That being the case, the olde "quality" argument has long fallen by the wayside, and in actual fact now falls in favour of many of its rivals.
But you do hit the nail on the head. We choose to subscribe to other services, the decision to get our wallets (or change purse in Accy's case) out is ours.
With the Beeb we have no such choice. We are compelled to subsidise it if we watch live tv, wven if we never avail ourselves of their programming. This being the case every programme should be top draw, every report should be balanced and unbiased, every show a triumph. But those days have ling gone and they are not.
So we are left with an imperfect choice. In this case I'll choose the capitalistsm because at least thats my choice. Sure, theres liable to be bias there too, just often in a direction that displeases a certain vocal segment. The big difference is that we're not being strong armed into a particular bias, its our free choice, and all the time we're getting the benefit of better programming.
On balance, ill take the better programming that I have chosen to fund, not the turgid same-old that I was forced to fund.
