That article is from December 4. The only review with some info I could find by notebookcheck written on 19 December claims the oneplus 13 supports both Magsafe and 50w wireless oppo mag.
They don't contradict each other. Every other article has also said it doesn't support Qi2. The only way you can charge it magnetically is theough the case.
Okay so not exactly zero, but until a heavy hitter like Samsung won't even consider, worldwide adoption is going to be low - their flagship just stuck with Qi 1, even though the standard existed for about two or three years at this point.
