You're technically right, but what things are versus how they're promoted or understood by most people (rightfully or not) often diverges, and therefore such "grounding" articles are useful, even if the wording addresses the perceived rather than the factual reality.

By way of analogy, if there was an article saying "I bought a 1Tb drive and it only came with 0.91 terabits", I think if you started explaining that technically the problem is the confusion between SI vs binary units and the title should really be "I bought a 0.91 terabit drive and was disappointed it didn't have more capacity", technically you'd be right, but people would rightfully eyeroll at you.
