So even without "human health and safety concerns", there are valid reasons for not showing graphic details.
That said, I absolutely think enforcing ethical animal treatment through public pressure on factory farming trumps right-not-to-know.
The public interest absolutely trumps some sort of business-model protection. In fact the only exclusions I can think of to that involve trade secrets provisions, but typically there IIRC there are fairly narrow definitions of what can be protected.
I'm not comfortable watching people be killed, but I'll celebrate American Independence Day.
I'm not comfortable with watching surgery, but I'll undergo surgery.
There are loads of things I benefit from that I don't enjoy watching.
EDIT: FYI, I have butchered pigs, chickens, and rabbits.
I am not comfortable watching women give birth, that doesn't mean I shouldn't have children.
If you're not comfortable watching a woman give birth, you can choose to avoid the many thousands of available videos. You don't have that option with factory farming methods.
Nobody wants to watch animals being slaughtered on an assembly line, but they should absolutely have the option to see what happens with their food. I don't think there's any moral room for "It would be disgusting and probably harm their business, so we shouldn't film it."
I don't know what that means. "Industry" is people doing the same thing. Doesn't matter if it's one software programmer or one farmer or a bunch of them.
There are few people outside abbatoirs (or indeed inside them) who can watch animals being slaughtered and butchered without emotional trauma.
Sometimes things are hidden from us to protect us from harm.
If you have nothing to hide, you have nothing to fear.
