There's a difference between filming the public in public-spaces (which is what the mass CCTV surveillance does) and reading everyone's private messages and every image uploaded from their devices. This is a step chance (if it goes ahead) and doesn't feel very different from what the Chinese State is doing to its citizens.
You refer to CCTV for state mass surveillance, and link to Wikipedia pages but it doesn't appear that you even read them.
> The vast majority of CCTV cameras are not operated by government bodies, but by private individuals or companies, especially to monitor the interiors of shops and businesses. According to 2011 Freedom of Information Act requests, the total number of local government operated CCTV cameras was around 52,000 over the entirety of the UK.
That doesn't make the UK appear to be monitored heavier than other locations when a single city in the US approaches half their total number of cameras.
