I didn’t check all of the people but picked 2 names at random and they were policy people not engineers.

Your first link is a set of experts that the EU Commission consulted while developing their regulations. It does not mean those folks were necessarily "behind" the regulations, so I would not call out anyone on that list.

Some of the folks on that list are certainly pro-scanning: it's an absurdly biased list. But to me that's reflective of the EU Commission having a desired policy from the start, then mainly seeking out experts who could help them achieve their goal.
