It's not gonna make you appear more professional if you don't call it DPad just because you are talking about a Nintendo game at the moment.
Journalists play many games on many platforms probably, it's a pointless distinction.
I wasn’t saying all journalists, but still, if you specialize in reporting on Nintendo stuff I’d expect you to get the terminology correct. Same thing for, say, a site that specifically reports on amiibo consistently getting the capitalization or plural of the word wrong—it’s like, this is the one area you’re supposed to be an expert in, how/why are you failing to use the correct official terminology repeatedly??
I guess part of why it annoys me so much is because it’s something that I pick up on and care about more than most and I just wish more people would care about correctness in these situations—especially when it pertains to their biggest interests—as much as I do. It may be a rather trivial thing when it comes to video games, sure, but I greatly value correctness in general regardless of what the subject matter is.
And again, as I already stated, I’m not gonna try to police what people choose to say colloquially (though I may try to bring the correct terminology to their attention in case they’re not aware), but if you’re in a position in which people look to you for information about a particular subject and are as such seen as an expert in that area, I would hope you’re using the correct, official terms so you’re not contributing to spreading misinformation. Like, it just takes an error from one person in a respected position to create a snowball effect and contribute to many, many others believing whatever was said is, in fact, correct and official when it’s really not.
And I can’t stress enough that, yes, the examples I’ve mentioned here aren’t really that big of a deal all things considered, I am very much aware of that…but that doesn’t mean correct terminology should be completely ignored, either, especially in places where you’d expect it to be used most. It exists for a reason, after all.
