This isn't the case. All the main financial institutions in the Channel Islands and IoM are global so they KYC properly. More to the point though: the information-sharing is pretty much gold standard (bank accounts have been shared for a while but now beneficial ownership of companies is shared too).

The only way to avoid tax is to permanently move there. And, if you are familiar with either of those locations, you should know that the punishment fits the crime.

Also: it is far bigger than Luxembourg and Cyprus. Malta is basically a haven for financial fraud. Ireland is basically a tax haven now. And basically all of the East European nations are targets given the weak controls of their financial institutions (and Denmark as it turned out).
