I got the impression it was aimed at people who see the benefits of both materials rather than implying one is better than the other. There seems to be a suggestion only scientists understand materials used in manufacturing too which is a strange claim. The post does contain some good points though and had it not been full of digs, I would have liked it.i think that post is directed at people who think these types of decisions are frivolous and/or not thought about, which is demonstrably false. they made the decisions they made for reasons they justified internally.
