The first Deadpool movie exists because of Reynolds passion for the project and the character. It was dead, and he brought it back to life after it got shelved. If he wants to make another one it'll happen, he doesn't really care about the money, it's about doing what he likes.I don't even think I watched all of Deadpool 2... it was fairly meh... Ryan Reynolds naturally carries the entire movie. Deadpool 3 could be the end because I'm sure Reynolds/Jackman are charging a huge amount, and they'll go ballistic with the CGI. The first two movies were fairly cheap compared to today's Disney standard.
Like Hugh Jackman, Ryan Reynolds cannot be replaced by anyone else to play Deadpool, and those movies are financially successful. I think some woke dork woman tried to make demands and Ryan basically had her fired from the movie lol. He's got a TON of power with that franchise, just like Jackman with Wolverine.
That said, Mr. Mouse needs to realize that the only worthwhile product they've made in the last several years is Deadpool and the franchise makes a complete mockery of woke/PC/SJW culture... what does that tell ya?
