no, nothing to do with announcements.
all you said could be right, but that does not change the fact that current witnesses froze private funds with no explanation. Is it a BS explanation or explanation that has more logic in it is something different.

old witnesses wrote the reasons, you can read them in my previous comment. new witnesses froze accounts with no explanation just because they can. so 20 people decided to froze funds because they don't like someone and 1 man made sure that no one can change that.
And witnesses are playing dead. users deserve to know what is the threat to the chain so they can act on it.
