Question about Deadpool and Wolverine

It's not just his suit, it's his skeleton. It's the corpse of an Ant-Man variant that was sent to the void by the TVA. Nothing to do with Fox.

It's a joke setup so that Ryan can say 'Paul Rudd finally aged'.

It’s a reference to the Old Man Logan comics, where Pym Falls was a town set up in the giant corpse of Ant-Man.

There's definitely a dead body inside that suit. It doesn't have anything to do with Fox, it is more just a comic book reference, which the movie has plenty of. Perhaps the suit can't be eaten by Alioth, so anyone inside the bones are protected.

It was a reference to the Old Man Logan comic books where Giant Man died in a battle, and now, all that's left is his suit and giant skeleton.

Quantumania failed

Not all the references were about Fox Marvel. There were a bunch of MCU references in the void too

Its a nod to a Wolverine Storyline, and a nod to the fact that they're in the MCU now, so all the MCU toys are available to them.

Its also a nod to "cerebro" which is spanish for brain and they were in Ant-Man's skull.
