Not Entirely Fair
People who only watch ITV are being forced to pay for the entertainment of people who prefer the BBC. And television is a preferred entertainment for those on lower incomes, for whom the telly tax is a great burden.
Also, this meant that unlike in North America, people couldn't use old TV sets as monitors for their computers without paying extra tax, thus making it more expensive to have an 8-bit computer there.
