A couple of points:
I wouldn't have, personally, posted the rumor. It's not like a ride or a show where if you get it wrong, you just take the L and move on. It's something you have to be close to 100% certain on due to its ripple effects. If you get it right, cool, your sources were right. If you don’t, it’s just causing unnecessary panic amongst employees and guests. To the site's credit - they clarified it was TM chatter and it was a rumor, but as someone who deals with this constantly; it's all about the headline. They'll ignore the "rumor" and focus solely on "Universal to close 2 days".
For years, we've made light, or have been skeptical, of TMs and CMs as sources of info and now we're treating it as a certifiable source for such an impactful news story?... and since it appears this talk was based squarely on TM chatter and not additional sources - it's bad form. Obviously the TMs are going to start chatting about what's next with all the cutbacks and VB/Attraction closures.
Beyond that - closing both parks on Monday and Tuesday just doesn't make sense when you consider that Tuesday would have all 3 parks closed. I also feel they would've announced the closures by now, or at least at the same time as the VB seasonal changes. Now, that's not to say a change or closure isn't possible because who knows in the time of Rona - but Universal's unusual public denial of a rumor leads me to believe it ain't going to happen as of now.
