The Isle of Man is a globalist tax haven and "crown" territory that isn't even part of the UK, what happens there has no relevance to people in the UK, just as in the Channel Islands. Thinking lockdown will be imminently lifted because it has been in the Isle of Man is false hope.
Of course it has relevance; that false hope is exactly the point, a carrot on a stick to say "Look, see what could happen if you too follow the rules as they did?"
Yes but it's not relevant in the way people think it is. Most people assume places like the Isle of Man and the Channel Islands are just normal parts of the UK, so they hear that lock down has been lifted in those places and get excited thinking that the UK will be next.
The reality is those places are not even part of the UK and were never even part of the EU, they are run as offshore tax havens for the elites. Normal British people can't even live in those places without a work permit, frankly what happens there is no more relevant to normal British people than what happens in Timbuktu.
