I have no idea what this is about, as “Dragon Rider” could refer to an abundant number of popular fantasy series, so I am curious to see a real answer about it.

I would have to imagine if it is anything like most other “drama” these days, it’s entirely meaningless and effectively just translates to a rage bait mine that one could try to exploit for ad revenue or imaginary internet points or something. Something people will completely forget about in a week.
