This is a puffed up congressman ruffling his feathers for the hometown voters and bored CSPAN viewers. As most congressmen do.
That said, this is a PR nightmare for Disney. After being a Disney watcher for a few decades, they absolutely hate losing control of their message, and their MyMagic+ message is slipping away from them quickly. The prospect of a sitting Disney CEO being called before a congressional committee, even if only in written format, to answer questions about a new theme park initiative that cost the company 1+ Billion dollars is disastrous. The press will jump on this, condense it into an 8 second sound bite and 45 second vapid "story" for the brain-impaired viewers at home, and the whole MyMagic+ thing becomes tainted goods worse than DCA circa 2001.
Disney is losing control of their message on MyMagic+, and for Disney that means complete disaster. It's a grey and rainy day today in Burbank, and you can bet a cold wind has blown down the halls of the executive suites with this little congressional bombshell.
