Apple was after “ios and downloadable code for vms/jits that we cannot control is a recipe for disaster” really. And it was.
Partly due to ios “security” based on appstore checks rather than technical ways (private ios apis, calls allowed only under specifically claimed features, and just bugs). Partly due to the fact that running something locally is prone to local vulnerabilities naturally (the same category as “never run curl | bash”).
The majority of downloadable code since day one of iOS app store, is native compiled code from C, C++, Objective-C, nowadays Swift.
The only dynamic stuff VM used by Apple is JavaScript.
Even the original lets make HTML5 apps went nowhere, as given the reception, it took less than one year for the official Objective-C SDK to enter the scene, and the whole HTML5 apps idea was thrown away.
