Is that really surprising at all? The government needs tax revenue for its budget. When it cuts tax in one area to bring about change, it either makes up the short fall somewhere else or it waits for the change to take effect and then makes up for the losses.
The same will happen with the TV license. It won’t truly be abolished unless they shut down the bbc or change the way it’s financed to match ch4. Instead they’ll stop the license and we’ll all be celebrating that we won, while they bump up some other tax in a stealth way to make up the shortfall.
