All of the answers to these questions are easy, and they all begin with a G.

G-code answers most of your technical concerns.

Why so incredulous about something that is obviously possible?

This is just a way to restrict individual freedom from corporate ownership. It's the equivalent of "for the children". If you're against guns don't fall for this bait, support some other legislation.

There are companies that sell small CNC machines marketed for the purpose of producing firearms. At that point all you need is the gcode and the stock.

When Apple launches a new product line there are typically no real competitors. When the competition catches up, their prices suddenly line up with what Apple charges.

Not saying we shouldn't pressure corporations to do better, but one of the unintended consequences here is that Apple's green initiatives and disclosures are in part simply a product of tight vertical integration. At a certain point pollution is simply resources not optimally exploited and extracted, and those inefficiencies are lost profits. Meeting environmental goals at that point will be easier for large conglomerates than for smaller players, thus encouraging the rise of more conglomerates.

Even taking your cynical view, is it not telling that Israel at leasts cares about the optics?

Just another opportunity for green washing. The Exxon report should just be a letter-headed page saying “yes”.

They currently offer 4 different families of iPhone for sale. The cheapest one is the SE for $429.

Samsung's record on RCS isn't great. Their Samsung Messages app didn't work across networks for most of last year. Like RCS only worked on t-mobile, but only for t-mobile branded phones, and for some time they couldn't send to AT&T. Not sure if Google Messages was much better during that time period.

Why would anyone want to stop using iMessage? It's honestly quite good and the app integrations are great. Honestly the only iPhone users I know who don't use iMessage are due to network effects (families in foreign countries where Whatsapp dominates).
