Storm in a teacup!
Get over it. If you're willing to wear a tin hat and cut yourself off from everything to avoid being snooped on then fair enough, you have a point to be made.
If you have a debit/credit card, a drivers License, utility bills, bus pass/travelcard/oyster card, mortgage, loans or finance of any sort, mobile phone, land line, cctv outside your front door and even step foot into most shops then you're being tailed. You're an idiot if you think otherwise.
Your telly is just one more thing adding to the already massive amounts of data being collected on you. It's too late to lose sleep over it now.
