Snooping on metadata is not a solution to chatcontrol.wtf either (although, these guys are greedy, they want all the data).
To quote the CIA: "We kill over metadata".
Metadata can expose very intimate details of someone's life. If someone attends a political rally, I'm sure that metadata's of no value.
If someone makes a call to a mental health hotline, or engages in an online equivalent, I'm sure that metadata's of no value.
If someone is part of a marginalized group the government or society frowns upon, that can be used to make them very miserable.
In fact, as these kinds of government agencies tend to look at the world primarily through the lens of people being "potential criminals", they might read the metadata in a very paranoid fashion, and easily jump to conclusions.
Alright. So, I think I've made clear that metadata has a great deal of value, and it's not something you want someone casually trawling through.
There are even messengers which go down the road of eliminating as much metadata as possible, such as the server having no clue of who is talking to who, and about what.
To some extent, Signal does this. Messengers like Cwtch are experimenting with taking it to a whole new level.
