Financial transactions in which the ownership of funds in question is changed through the transfer of funds that do not include any other services are excluded from VAT. Chipmixer would simply act like those coin machines in which you dump all coins and you get a banknote or the other way round.
There's no VAT on exchanging money, right?
It is true, I had not thought of that, but I imagine that it does not operate as a regular company of which the Ministry of Finance of the respective countries have record, and less operating with Tor, I would not see much sense.
This isn't an argument to stop using mixers, this is an argument for a revolution.
This is crazy, I don' understand how people accepted this rules 
Why? They don't have anything to hide. 
Forget about revolutions in Europe to defend privacy. People accept it because in those countries it does not affect them and they see it as a measure against the rich. In those countries, the average monthly net salary is around €1,300. Add to that the fact that people have a mortgage, a car loan and some credit card or personal loan debt, and that they pay more and more frequently by credit card or cell phone, and you get that the vast majority of people have not seen €1,000 in banknotes in many years. Add to this the mentality that the state is the best guarantor of citizen welfare, and you will see why no one protests.
Back to the central topic of the thread, I agree, especially with stompix who has explained it very well, that the exchange does not have the legal capacity to hold some funds that it suspects are laundered without informing the authorities, but I have been reading the comments on:

and something doesn't add up:

As we told you before, your funds has not been credited to our account, so we are unable to return them. We will be happy to do it when it possible.
Are they saying that it is an entity external to Openchange that has freezed the funds?
