Not the opposite, but we're missing the simple fact that enterprise products would rather get more features out over micro optimizations. There are constantly clients bringing their demands for additional features or major fixes, very rarely are they "please optimize the UI". For consumer facing products, that's not really the case, unless some massive features are missing, they would rather things be snappy as they tend to be extremely distracted at all times so dropping your app/site/whatever is no big deal.
During work, what else are you going to do if Cloud UI is slow besides just wait? Go through the entire process of trying to convince management to make a switch because UI is a little clunky? Good luck with that!
