So recap. TV licences is forced and sky TV is voluntary subscription based.
Absolutely right, but it's a bit more than that. Things are only ever forced upon you if you let them.
First you have to realise that every document you receive through your letter box from the state is an "invitation to contract". TV license, electoral roll, child birth registration, yada yada. By filling in the document and signing, you are entering into that contract. In the case of TV license, you're entering into a legal requirement that you pay a fee to them to permit you to watch live BBC channels. As long as you pay this, you won't hear a peep out of them.
This is done by intimidation and threats through the post. Most people succumb to it and just fill in the form, setup a direct debit, job done. But in reality, you do not need to do this. The unfortunate bit is, if you don't, you will then be constantly harassed by post, and even a visit from an "inspector" who then tries to "force" you further into contracting. Not to mention the attempts they will stoop to in order to scare you into contracting (fines, court summons etc). But remember, even a court summons is, yup, you've guessed it - an "invitation to contract". It's inviting you to visit their "place of business" to discuss why you haven't been playing by "their" rules. Deception at its best.
Of course, you could fill in the form and say "I have no TV, so no TV license required". But you still have to sign if you do that, and that's another contract. If they find out you have lied, they can legally fine you and have you again for that.
It's a farce really. I see why the TV license had some purpose and credibility in the early years of TV, when the BBC were
the only TV company in the UK. But times have moved on. If anything, it's an unlawful way of extracting money out of gullible people who do not know their rights, with that money going straight into the back pockets of a very corrupt organisation. I personally have very little respect for the BBC now, given that they employed Jimmy Savile for all those years but still continue to do their "nicey nicey" Children in Need party trick every year. Honestly, they should just shut up shop and die, and take their TV license with them.
