I think it's important to note that this is happening because of a govt decision, not a BBC one. It feels like a lot of people are 'against' the BBC these days, which I find very sad, as personally I'm very proud of it indeed. I suspect we would lose something culturally significant if it were lost.
Like a PP, I also find the ageism in these discussions very depressing.
Many, many older people are poor. My own parents - who worked all their lives - are quite poor, don't own property and are very elderly. I don't know if they get pension credit (they probably should) as they are private about money and quite proud.
