This was always the case though, so nothing new. Instead of seizing to sell, they seize to keep. The risk was always present, people were just ignoring it. The not your keys not your coins lesson comes one way or the other. If a person can't learn by reading, they will learn by losing.
It's incredible that even after 15 years since the existence of Bitcoin, a lot of those who own Bitcoin have not learned anything, so they still think that CEXs are some kind of bank where you can store (in a safe way) your cryptocurrencies and nothing bad can happen. Will people ever understand that no government in the world will accept Bitcoin for what it actually is, but rather they accept it by changing its purpose?
It will probably never happen, but as the old saying goes,
"While I breathe, I hope"
