I actually get where they're coming form with this... because I'm a fan of Tobasco Hot Sauce and know a little about how and where it is/was made and the history of the company.
For anyone who doesn't know and cares to:

With that in mind, the salt dome and the hot sauce and it being tied in as a Louisiana thing does make some semblance of sense if this attraction is sponsored by the McIlhenny Company and they will be the ones bottling the souvenir hot sauce being sold as Tiana's... and if guests are familiar with all of this.
But I'm guessing the makers of Tobasco sauce are not sponsoring this. I'm also guessing that since I'm the only person that has so far recognized this connection, that it's not going to click for 99.9% of guests, either.
And also, that real-life salt dome (along with any other) looks absolutely nothing like the carcass of Splash Mountain no matter how they try to paint or decorate it so unlike the real stuff, this is all, as they say, pretty weak sauce.
Then again, the circumstances around why that salt mine shut down in 2020 may be reason enough for Disney to not want that connection to be obvious as guests ride through this one.
