You are looking at techniques to accomplish the same thing. One works poorly relative to the other, but the results are roughly similar. One is easily blocked the other is not. So as a technique, yes Tornado mixer is a worse approach.
My problem is not necessarily with a centralized mixer but with the regulations that make using a mixer a prohibited activity. But in the current environment, absolutely that Tornado mixer getting banned should not come as a surprise to anyone. We knew governments would fight back. And not only will this be the extent of it, I am pretty sure they haven't even yet begun to fight.
