I would take this latest information with a grain of salt. Nothing worth the money the Alien and Predator franchises are will be dissolved the way this information suggests. If DISNEY is that set on doing away with it - and I still think they will sooner consider finding a more PG-13/Stranger Things-like approach to it - they will simply sell the rights to someone else.
Why on earth would they just do away with an entire profitable franchise or something that makes that kind of money? They will simply sell the rights to it.
Also Im not sure the reporting is clear. DISNEY PARKS have considered ALIEN family-friendly enough to include in their parks for decades. Lets not get carried away. They arent gonna throw out the baby with the bathwater.
Consider this: ALIENS w/o the cursing, is likely a PG-13 film by today's standards.
