I am pro the fee too (have lived in Germany, Belgium, Sweden now the UK). Honestly - if you feel that there's only crap on the national stations your missing the gems that are there and that are, indeed, by and large absent from the private stations.
Things like
In the UK: Panorama (
http://www.bbc.co.uk/programmes/formats/documentaries/schedules), a whole lot of support for cultural organisations through the BBC (
http://www.bbc.co.uk/performingartsfund/) as well as helping out independent film (
http://www.bbc.co.uk/bbcfilms/recentreleases/) and a whole host of other services (as I am studying for my MA in Writing - things like BBC Writersroom ARE damn useful). Oh and I LOVE BBC radio four.
In Germany: Arte (
http://en.wikipedia.org/wiki/Arte - also France), the channel I miss most living abroad. Arte also sponsors and co-founds an amazingly wide selection of really good indy movies. You'll notice the logo popping up in cinema quite frequently. Or - programmes on ZDF like 37 Grad, auslandsjournal, Frontal 21, aspekte.
There's a wealth of public programming that is well worth it. Sadly - a lot of it does not attract a lot of viewers - so it's no surprise, really, that the more popular stuff takes prime time; these state funded broadcasters frequently have to justify their existence to politicians and the public: a decent prime time audience share is what keeps them alive. Arte, in particular, is a case in point for a channel that really focuses on art/culture/intellectual style programming almost exclusively; yet the audience share is below 1% in Germany, below 3% in France. That old conundrum that people demand more "quality" and "cultural" things from the state broadcasters, but don't really seem to actually want to see it :/.

Edit: On the - and yet the state programmes are taking advertisement money to fund their programmes - yeah. It's creeping in over the last decade; a lot down to mismanagement and ever further slashed funding. THAT are things to protest against, IMO. Not the fee itself really. Just as with any tax / state fee - it's not the taxes that are the problem, by itself, but that there's not enough pressure from the public to actually make sure there's accountancy of how they are spent, and that the rules are upheld.
For me the Scandiavian Countries have it right, really. Sweden (I've been there for five years) DOES have high taxes - but it is both a much clearer tax system than any other country I've lived in AND what happens with the taxes, what they are spent on (including polticians own tax declarations!) is much more transparent than anywhere else I lived. No country is perfect, mind you, but knowing what happens with the taxes you pay, seeing them actually put to use makes it much more acceptable to pay those fees. Both UK and Germany have much of a tendency to moan about taxes and, to me, for the wrong reasons: Complaining that they have to pay tax at all, rather than demanding their taxes are actually used in a sensible manner.
