I find this to be a little uneducated. You don't work in theater or live entertainment, else you'd understand how this statement is not only ridiculous, but offensive.
Technologies like close-proximity flame effects have a lot of hoops to go through. Everything from Safety Committees, to (government employed) Fire Marshals can take an effect out of show for various reasons until they are satisfied with the end result.
If you payed any attention, you'd realize that this parade uses a new method of float tracking that negates the need for "Bed-Loops" such as the one in Disney's Electrical Parade. The parade communicates in real time utilizing data from GPS, NFC, and a host of other technologies to recognize where it is. It relays this information to a server which adjusts the area music (not just the music on the parade units) to the correct track. This has never been done before. By anyone.
When the iPhone debuted in 2007, it had a host of problems. When the iOS 7 update was released, it had a host of problems. Technical glitches are common amongst new, groundbreaking technologies.
If you're going to "hold Disney to the standards they used to hold themselves to" then you should understand that Disney no longer aims for the same standards. Lawsuits, new technologies, increased capacity all play a part in why Disney makes the decisions it does (mainly lawsuits and liability).
This new parade is phenomenal, regardless of the technical glitches it has in it's opening week. I honestly can't think of any broadway production I've been a part of that had a flawless first week.
