It's not obvious to me that these poor people would be better off not recycling the e-waste. I certainly wouldn't fancy doing it, but if the alternative was starvation for my family I might consider it.
I'm not at all sure that it would benefit the people of Ghana if there was no e-waste.
As for dumping toxic waste that's a problem enabled by government/courts that don't function properly.
Further it's not clear in the video how the e-waste gets there. There's the implication that the West simply dumps it there, but clearly the governments of the West don't do that, nor do companies like Apple. Probably what happens is that Ghanian companies import it from e-waste collection companies in the West.
When I am looking for a product to buy, I don't wish to have a political debate or have someone make any assumptions about where I stand on various political issues.
We might not like the thought of them working with e-waste but until we provide them with a better alternative it's not right to remove their best opportunity to earn a living.
Your prescription may have been switched ;-)
I think a reasonable philosophy is "clean up after yourself". I see no problem with advertising a product being able to easily meet that goal.
