I think that's the point that people are objecting to.
The orange dot doesn't total the presentation the way a totalled-car in a crash does, certainly not necessarily. It's NOT worse than nothing. It's not like a shopping cart for commuting to work.
The point of the replies here overall is that those things are hyperbole. It's NOT about nit-picking the language. It's "well, technically, the car will still drive in this case", it's saying that the orange dot DOES NOT ruin presentations that badly. You can ACTUALLY and PRACTICALLY present with the orange dot.
A better analogy: your nice car gets a rock through a window with a noticeable hole and huge cosmetic crack. You say "I can't drive this now! My car is useless! It's totalled!" And people are like "Dude, it's not totalled." And you say, "This is my professional car for business, I can't show up with a cracked window!" and People are like, "well, you could actually…"
It's not like the software has a bug that inverts all the colors, and people are saying "you could in fact do an inverted-color presentation, it's possible". It's JUST a little dot, and it's bad, but it's NOT as bad as the hyperbole.
