All very dubious
Seems like a deliberate ploy to intermingle the free & non free components, so the non free components are inadvertently used without the user being aware of licencing issues.
Thats why the timescale was long.
A bit of time to stop the fully free Java stuff being possible to easily obtain as a separate entity.
A bit of time to create a "contaminated" Java with free & non free stuff inter mingled & make that the only Java download available.
A bit of time for use of the contaminated Java stuff to rise as people patched / upgraded.
Fast forward to now, lots of users will by now have inadvertently used a non free component, send in the sharks to fleece them of cash.
I'm sure some half competent lawyers could mount a robust counter attack based on the inability to easily get an uncontaminated wholly free version.
