Long story short: he was trying to find the password for his own vacuum (yeah that already sounds ridiculous) so he could control it with a game controller, and found that the same exact credentials worked for an estimated 7000 other vacuums that need to call home to process visual data in the cloud. Hidden behind the lede: DJI automated vacuums require constantly sending their footage abroad to even work in the first place

I guess computing also abhors a power vaccuum!
