I imagine it's more of a population issue (Destiny)

IB and Trials will get very static for legacy consoles because they won't have any new gear. After one or two passes everyone will be at max level, and then what is the point over normal crucible?

It sounds like they are just preemptively eliminating that complaint.

I'd also guess that they take a small amount of actual people doing work on the backend to activate and organize, and they've decided they no longer want to have some of their team working on old hardware instead of the shiny new stuff. Plus having people who like those events know they the events are going away may help spur them to upgrade (for the record I do not believe this is the primary motivator nor do I suspect intentional coercion by removal).
