So given that the word doesn't really apply to hardware, I believe they used it correctly (100% means the set of things where it makes sense to be used) and are not misleading. In fact I strongly dislike some of the "open-hardware" marketing of some previously mentioned devices, when that is obviously false and misleading.
It's a blessing and a curse. Look at package managers, they more or less all do the same thing, with one primary job of "go download some binary so I can run it", yet there's so many to choose from. Every time you read some Linux guide they have to list 7 different ways of installing the same package. It's stupid, probably even more so for the maintainers of those packages because they have to distribute their package 7 different ways. At least I'm glad systemd has mostly become the standard, so you don't have to also see 7 different ways of creating a service.
It takes a certain linguistic skill to convey the sleight of hand in display in such maneuvers. But once you're grasped it, you can easily spot it and almost predict what the next set of actions is going to be.
As an aside this applies to a wide variety of places like corporate settings, negotiations, sales meetings, city council meetings to mention a few so its generally useful to know.
When I visit every few years, it amazes me how quickly Europe is “Americanizing”. More fast food and less traditional food. Ripping up vineyards that have been there for centuries. Fewer protections for your farmers. More people walking around staring at their phones and less people talking to each other in cafes. Seems like almost everyone dresses like Americans and can speak English now. And it’s hard to tell the difference between the coffee shops in Spain and those in San Francisco. How long until you start building suburbs and driving everywhere?
Don’t get me wrong—I love the U.S., and I love living here. But its culture is not for Europe.
