I wonder why they went with WYSIWIG in the title despite having WYSIWYG in the article. Anyway, hard to blame the folks who invented it, since it was early days, but WYSIWYG was a truly terrible idea. It heavily implies the need (although, doesn’t technically demand it) to have user input produce only local changes, so we’ve been cursed with all these office documents with terrible spacing. It also ruins our ability…
You're mistaking Microsoft's specific implementation fumbles with an interaction mode that helps billions of people every day. Don't throw the baby out with the bathwater, there are plenty of good WYSIWYG implementations out there.
