FOIA doesn’t usually involve my personal data as a typical private citizen. Personal data that can potentially be traced back to me and affect my life in negative ways. It usually involves data about the work that the government itself is doing... work that is funded with my tax dollars and involving data that ostensibly can’t be used to harm me personally. Data sharing increases the attack surface for that data... considering I never consented to that data being collected in the first place, the supposed government of the people should be working very hard to make sure my data isn’t abused or hacked.
Agreed on the latter statement though.
