That's not how capitalism works.
Between green and more profit, it will always pick more profit.
The green "recycling" etc is just ecology theater. Recycling = tons of parts just ending up in China (under "recycle" programs where they're paid to get western trash), where most of it is discarded and thrown away anyway.
Absolutely. If your customers start choosing you rather than your competitors due to your green credentials, then in can lead to more profit.
In exactly the same way that Apple is gambling that security will lead to more profit, despite the fact that selling customer data is clearly a profitable short term opportunity.
Yeah, that's not gonna happen either. That will be the last concern of the majority of consumers...
And of course companies need to sabotage their sales (tell customers "just keep upgrading your existing model, buy less, etc") to get those actual (not ecology-theater) green credentials, which no company and no competitors are gonna do either.
