They go a long way to keep photos and documentation of conditions in manufacturing facilities private and only show off staged facilities in Cupertino etc.
It looks like Apple already goes above and beyond in comparison to many western companies

For the last decade+ most reports of child/illegal labor conditions in factories that manufacture apple products have sourced apple's own supplier audits, which is super great as a message for other corporations: if you audit companies and discover and report illegal conditions (and terminate contracts due to them, which apple also does) all the reporting will be "this company employed child labor"[1] etc.
You also get failure to understand scale of companies like Foxconn. Recall a few years back when everyone was attacking apple due to a spate of suicides at Foxconn factories, despite the suicide rate being lower than the rest of china, and iirc most US cities. The problem being the reports were "X suicides at this factory" but not including "this single factory has 400 thousand employees". On the plus side the reporting meant apple forced Foxconn to address this "problem", but that involved things like suicide nets, so I don't know if that included steps like providing counseling, real therapists, etc.
So most of the suppliers/manufacturers apple uses (esp. Foxconn) work for _every_ tech company, but apple is the only tech company that does supplier audits, and requires suppliers to compensate victims (and for kids, requires them to them support the kid's future education), and so is the only company providing regular reports that let reporters produce sourced articles saying "Apple employs children". Note of course that if apple and google use the same supplier, but apple is the one doing an audit, and publishing a report, those articles will not reference any other company.
Now all that aside I want to be clear: do not think I am saying (nor think) Apple is a spuriously "good" tech company. Most studies basically say all corporations are psychopaths if you analyze them as if they're person, and Apple is a corporation. 15-20 years ago there were lots of reports of apple suppliers being terrible (abuse, child labor, etc, etc) which apply to every other company but articles about apple get press so that's the reporting. It would be naive to think that absent that reporting apple would have started its audit system. The reality is Apple is more acutely aware of (and maybe impacted by?) its market image than other tech companies, so Apple started audits to ensure it does not get that bad publicity. That reducing child labor, reducing worker abuse, etc is a "good" thing for the victims is just happenstance in this context.
It's depressing that despite the clear overlap in suppliers only a few companies perform any audits (a quick check of the big tech cos seemed to only find apple and google publishing supply change reports, though there's a lot of overlap between the two).
[1] The child labor thing is fun when you look at the republican states in the US that are aggressively pushing for child labor to protect those poor businesses from the invisible hand of the market requiring them to pay market rates for labor.
