Similarly: International aid groups dug wells in Pakistan to alleviate sickness from contaminated surface waters, such as rain water collection. It was successful and dramatically reduced incidence of illness and death from that cause.
It also led to widespread arsenic poisoning from many of the wells.
Actually improving things is tough and even if you succeed, people will focus primarily on any unintended and undesirable consequences. People almost never mention that the wells in Pakistan achieved the intended goal and I full well expect to be met with open hostility and accusations of some sort (apologist, downplaying).
There may well be good reasons to not be more even handed in presenting such info. Or there may not be.
When we start with a presumption of guilt and looking for someone to blame for presumed intentional malice, it frequently interferes with moving towards solutions. Even if you can find someone to blame and successfully indict, it typically doesn't fix the problem.
Few people focus on fixing the problem and trying to discuss solutions is often met with vastly more hostility than finger pointing.
