of course, but that's not an issue with "the government needs to not be able to hide anything". you can't just nitpick some examples of where it may do good to justify the position – you open an entire can of worms with the vagueness. should they have to disclose a list of all the people theyre keeping tabs on, how theyre doing so, and the info they hold on them? that would be extremely dangerous for society. should they disclose the exact methods which they use to track people? again, you're just showing the people they're tracking (for good reason) how to avoid being tracked. if you just want no backdoors then say "we shouldn't have government backdoors", but the only way to properly ensure that the government isn't illegally doing so is by exposing a whole lot more stuff that may not go so nicely.

i don't want the government surveilling me illegally, but i find it reasonable that the government can hide a lot of stuff for the sake of all safety. i also find it reasonable for them to be audited extensively. do I trust the government? lol no, but i can't complain about the government not previously keeping tabs on obvious shooters, then say i don't want the government keeping secrets like that... it's one or the other.

obviously many specific things shouldn't be able to be hidden by the government. but you're painting with a broad brush
