I think an argument could be made that DC does exist in the Foxverse. In 2, Deadpool says to Cable “You’re so dark… You sure you’re not from the DC Universe?”. Later DP time travels to kill Ryan Reynolds before he makes the Green Lantern movie (and note, killing Ryan Reynolds in the past doesn’t cause future Deadpool to cease to exist, they’re two different people). Makes sense since no non-mutant superheroes from Marvel exist in the Foxverse, DC operates without a rival. Also, this is a nerdy shower thought, take it as you will.
it’s my personal belief that competing franchises should acknowledge each other as fictional in each other’s universe.
Marvel should have DC comics in universe, and DC should have marvel comics as well.
And star wars should be an antique franchise in Star Trek,
I think it would be hilarious and a big-dick move to establish Star Wars as a canon piece of fiction within the Star Trek universe.
Just imagine the opportunity for holodeck cameos?
Star Trek and Star Wars are in the same universe.
Star Wars just happened a long time ago in a galaxy far far away.
After some shenanigans Han Solo even came to Earth once and met Indiana Jones.
Technically Chowbacca is Bigfoot.
Stargate SG-1 characters reference Star Trek several times throughout the series. Star Wars too, but less often. Also there’s this.

This is just one of many references to DC comics in Marvel. This is just the most recent and I think the only one in the MCU
Edit* and in the 20th century fox X-Men movies, the X-Men comics exist in universe towards the later movies.

Deadpool shouldn’t count for canon things since he can break the fourth wall.
