Ok... that title should have a comma, not an em dash. If you're going to complain about having them being removed, you have to use them properly at least.

And then " It seems I have two choices now—keep using em dashes with a sort of stubborn, curmudgeonly pride until all my clients stop exchanging money for words, or start writing incredibly long run-on sentences, like this, with commas all over the place … and maybe ellipses too; ideas connected by semicolons. "

That should be a colon after "two choices". (There's also clearly more than two options, one of which does not involve run-on sentences with his otherwise poor grammar. James seems like a shitty prose crafter if he's unable to avoid run-ons.)
