I think this was done mostly because Blender is Russian based mixer, and with current situation everything that comes from that country is considered bad.
This world we live in today is starting to look more and more like one from George Orwell's book 1984, ''War is peace, Freedom is slavery Ignorance is strength''.
Now that people are fighting each other who is wrong and who is right, they can go ahead with their plans and control everything and everyone more than ever.
Is anyone else worried about what may happen if you move funds from a mixer to big exchanges after this? Of course one could always do another hop to "unlink" a set of coins from a mixer, but how many would be enough?
Best solution would be not to use centralized exchanges that can one day block your account or seize your coins just because of your haircut, way you walk, or because you speak anything against government.
Using decentralized exchanges and P2P trading is always possible and I know people are doing face to face trades more than ever, but using anything else you should be ready for anything to happen.
There are some tools we discussed before that can check if addresses are ''tainted'' and risky or not, but I think it's all bias and controlled by some central authority.
If you think this is bad, what if in near future we have CBDC crap that can be spent only for things that is allowed to be spent in specific time period and than it's gone, that is next level craziness and they are working on it.
