Harry Potter Summoning Spell is Near Lightspeed.

Well, fact stands above. JK Rowling wrote it doen herself.

Here, her statement:

Rowling's answer: "'Accio' only works on inanimate objects. While people or creatures may be indirectly moved by 'Accio-ing'objects that they are wearing or holding, this carries all kinds of risks because of the likelihood of injury to the person or beast attached to an object travelling at close to the speed of light."

This messes up a lot of stuff in my opinion. Mainly because HP Characters now can just summon things from behind people. And this stuff makes a lot of feats in the books really questionable, like the Battle of the Prophecy.

Already brought up. It was rejected on the basis of it being stupid and contradicting the series, since Harry could react to an Accio'd object and had to wait a full minute for one to travel ~200-300m.

Feats > WoG > Statements

Yeah, basically what he said.

Thank you very much. I really dont know Why JK did that...I mean, Newt would have been murdered by the Gold Coins he summoned.

If it's from official interviews, we tend to accept Word of God if it doesn't contradict the series or simply clarifies what happened on-screen.

If it's from Twitter, we tend to reject it due to the fact most authors don't like being bothered and answer questions like "Is Character X a universe-buster????!" with a "yes" just to appease fanboys.

Even if this was true, the object is the only thing pull at those speeds, it won't give anyone reaction to those kind of speeds since is more like aim-dodge or aim-catch is that is a thing. The accio feats in the books are accurate with her statement about the speed, the movie feats are not. And "close to the speed of light" is vague.
