Well, if we accept for the sake of argument that Glyphosate causes cancers at a very low rate, then its use would still save lives.

So there's that too.
But as it doesn't, it's saving a tiny fraction more lives.
Again, this was not a case where studies of dietary intake should be considered highly relevant, since farmworkers are subject to much higher rates of exposure before the chemical breaks down in the environment. You have to look at the facts of this particular workers' exposure and how the packaging instructed people to handle the materials. If those workers needed to be wary of prolonged exposure, then their employers would be responsible for safety guidelines such as use of goggles and protective clothing. If Monsanto did not provide such warnings but had suppressed internal studies or ignored published ones that might have suggested a need for them, then the plaintiff had a case for damages. I don't know that that is how things came off, because neither of us has actually looked at how the cases were presented in court.
Whether you like it or not, courts have a responsibility for determining liability in such lawsuits, and both sides had a chance to make their case. Juries don't always side with plaintiffs in such cases, but there is no reason to get so outraged over the outcome of this trial. Your judgment is based on what you've read about glyphosate, not the evidence presented in the trial.
Either way, fines and bans are fucking stupid.
This isn't really about banning the product, but there can be lots of good reasons to ban some chemicals and products. It depends on a cost-benefit analysis. However, this case is more of a worker safety issue. The legal question of liability was what was at issue, and, since there seem to have been punitive damages, it looks like the jury felt that the defense may have engaged in some deceptive practices. Again, it is hard to tell from the few superficial accounts of the trial.
