The U.S. Tomorrowlands have always had attractions that never really belonged. Corporate showcases, attractions that didn't fit anywhere else, forced IPs, futuristic tech that eventually becomes outdated... Tomorrowlands were always a thematic mess. Sure, a handful of attractions could be named that fit the idealism of the theme of "Tomorrowland", but they have always been surrounded by attractions that didn't fit. And this has been true from the original Walt-created version.
Aspiring to thematic purism isn't bad, but let's remember: it has never been achieved. There's no backsliding... it's always been this bad, with some periods worse than others. Let's just hope for a brighter tomorrow.
