Because the language I'm reading here doesn't mean anything.
"Researcher" can mean anything. In the US we see DOGE people rifling through government finance records, pipelining the data to the executive, for targeting of specific political interests. "Research" means whatever the present democratically elected regime wants it to mean.
"Systemic risk" can mean anything. Last month in the US, millions of "undocumented" people were walking around relatively unconcerned. This month they're all a "systemic risk" and being actively hunted down for deportation or worse.
Maybe tomorrow you become a "systemic risk," and whomever is in elected office at that time designates and funds some academics to "research" all your X/Facebook/Mastodon/whatever activity. There is a non-zero possibility in Germany that AfD will one day get to designate what "research" means and what the "systemic risks" are. How does that sound?
So it's not the least bit difficult to understand why members of a supposed democracy might think this isn't a power "researchers" should have. It's only a problem for the naïve, who suppose the future is governed by only the right people.
