Sure, life-extension is a nuanced question, but the topic under question is whether we should
ever criticize the person presenting an "outside-the-box, maybe un-PC" idea, rather than criticize the idea itself.
My mining company example was much closer to the kinds of ideas that are actually pushed by people in the real world, quite frequently, more so than the article's anecdote about life-extension being criticized.
I'm saying that some people seem to pursue profits in such a way that they clearly have a moral framework that doesn't match mine, and arguing over the ethics of the idea with them is fruitless.
Did whoever it was at Volkswagen who had the bright idea to make cars have a system to detect when they were being tested, and change their emissions accordingly, really need someone to debate with about the ethics of the idea? I don't think that was a case of someone with a simple lack of knowledge of the ethical arguments.
These are the kinds of "innovations" people are coming up with in the real world, more-so than life-extension. People are going to create new apps that allow microloans with Bitcoin, with usurious rates, and market them to poor people. People are going to create dolls that listen to your kids and use the info to market toys to them. People are going to create devices to allow you to monitor your health, and sell the info to drug companies, or even to employers. There are going to be plenty of Bad Ideas where the people peddling them know the ethical arguments against them. At some point, we get to criticize the people coming up with these ideas as well.
