If Visa and MasterCard are promoting and implementing Bitcoin, who honestly cares about Tesla not accepting it?

I honestly can't connect the dots on how quickly the price dipped solely on one man whose intentions are as clear as day, it was all going slow and steady with good news after good news coming from different sources and all of a sudden this car industry doesn't accept btc payment and peaks -14% in 3 hours??? If anyone can explain how this kind of news influences so much a decentralized network??

(Not complaining about the dip I actually just bought even tho I am bummed that all my purchases were at a higher fee. I'm just complaining why a single person has this much influence on a global network)
