How to enable multiple objects at the same time?

For some reason a 2.79 file opens with 100+ objects disabled in the viewport in 2.8 (the monitor icon).

How do I enable these without clicking 100+ times?

(Also, why doesn’t control click show/hide the entire hierarchy anymore? Even if you prefer the new “isolate” functionality, it’s insanity to not have it made a toggle. Like, how do I undo my Outliner control click in 2.8? Plus, why remove the show/hide hierarchy feature alltogether, why not put it in alt click, for example?)
