Most of it's boring

Quoting sources

Copy/paste. We all do it, and don't try to pretend that you don't! It's especially useful for direct quotations, as the surest way of not screwing up. So, there's absolutely nothing wrong with copy/pasting—provided that you're not breaking copyright laws, that is.

BBC journalists strive for accuracy deadlines, and a little copy/pasting obviously helps them achieve that. Again, nothing wrong. But, I do get annoyed when they insert a tweet into an article, and copy/paste its contents into the main text. This duplication is unnecessary; it wastes the readers' time and viewport space, particularly on mobile, and is utterly pointless. Embed the tweets, or quote them. Make a choice.

I believe that the journalists in these cases are just taking the piss. Whether or not they're using a bottle is another matter.

You don’t really believe the peeing in bottles thing, do you? If that were true, nobody would work for us. The truth is that we have over a million incredible employees around the world who are proud of what they do, and have great wages and health care from day one.

There, I can copy/paste too! Aren't I a clever boy? But does it add anything new and meritorious? No, I didn't think so.

You make the tax laws we just follow them. If you don’t like the laws you’ve created, by all means, change them. Here are the facts: Amazon has paid billions of dollars in corporate taxes over the past few years alone.

Once again, I've ably shown myself to be a smart arse. Seriously though, these are full-screen mobile screenshots; admittedly, they're taken on an iPhone 6s, which doesn't have the hugest screen.
