One bumper harvest opportunity for the TV Licensing bullies came a few years ago, after the ruling changed to take away automatic free TV licenses from people aged over 75.
It was a very mean government decision in the first place; it would have been much kinder if they'd removed it (if they absolutely had to) so that people approaching 75 would just never get it, but leave current claimants to continue getting it for the rest of their lives. When you get to a certain age, many people rely on receiving concessions to help them make ends meet in their retirement. It can be very jarring and worrying to have qualified for a benefit on the basis of older age, and then to suddenly lose it.
However, they didn't just send out letters to the old folk explaining to them that the law had changed and so they would now have to begin paying again, IF they watched TV; rather they sent out their standard "You are a bad, dishonest person and we will hound you and you could end up in court if you don't pay up now" threatening letters.
Obviously, a great many of these letters were sent out to people in their 80s, 90s and older - on the whole a vulnerable demographic who are less likely to be online to find out the facts for themselves and far more likely to be suffering from confusion, cognitive decline and worse.
My DGM, in the time between when my DGF turned 75 and when the TV licence ruling changed, had been widowed and had experienced a big downturn in her (already bad, lifelong) mental health, accelerated by her age and concomitant vulnerability. Ironically, she had actually come to hate and fear the TV and refused to watch it, because of her paranoia that the people in the TV were talking personally to her - she'd insisted that we take her TV away. Yet still, TVL continued to send her these nasty 'you are a criminal' letters, when she was well into her 90s. I'm sure her story is far from unique in principle. I don't think most people would necessarily consider this a respectful, honourable way to treat very elderly and often vulnerable people.
