Those are old SHIELD files, released by Black Widow to the public. Zemo didn't hack SHIELD.Doesnt mean that Stark didnt find out or cant find out.
In Cap: Civil War
Zemo goes thru Shield encrypted files to find answers
But Tony...aka the king of hacks...doesnt hack into and encrypt those files for himself?
Still, SHIELD is doing things that are public enough to draw attention, like extracting people from everywhere (even inside trains), or daisy tossing cars around, etc., but then again, those actions might publicly be attributed to the ATCU, rather than to SHIELD. Still, Stark might know some things about SHIELD that won't come up in the movies. Who knows?
