Nobody is judging - they are only stating the fact as to what the law says. The democratically passed law, in this case, states that if you are in receipt of any State benefits, you are required to inform the DWP of your address abroad, if you are living outside the UK for 3 months or more.
That is the law. If you decide not to adhere to the law, then that's upto you but you must be ready to take the consequences, should the authorities catch-up with you.
