This is my breakdown of the "experts" on the list:

U.S. academic I don't know a whole lot about. Haven't heard of him, though keep in mind that Ylva might be taking his input and tossing it in the trash. In fact, this likely applies to many of these, she's probably just picking things she can use to justify her proposal.

U.S. academic associated with Microsoft.

U.S. academic who used to work for FB / associated with government.

European academic who opposes the chat control.

Nine from two U.S. Big Tech firms.

One NZ tech company.

Five Thorn trying to sell their software.

Four pseudo-governmental. Nominal NGOs deputized to carry out police / government functions.

Seven governmental / police.

Two spooks (CIA / NSA type agencies).
