I've never heard of this person before. But I will warn that people agreeing with him doesn't mean anything, there were several people on this site "confirming" the yeti was working the other day when that twit posted about it.
Glad to be wrong as usual when there's broken effects that could be fixed, but i'm going to need more confirmation than just some dude on twitter. I'm guessing that reinstating lasers that were physically removed is a little more of a chore than just replacing some bulb or whatever. I guess it's possible this could have been done overnight or something, but i'm still skeptical until we get more concrete information and evidence.
At this point though, i'd like nothing more than to be wrong about things like this. It gives me no pleasure at all to live in an age where we're always wired to expect and assume the worst from Disney World and that people on Twitter are just screwing with the emotions of actual fans. It's a sad state of affairs when things like this aren't just assumed to be true. I can't tell you how relieved and happy I would be if this trend started to die.
