Isn't Demon Slayer series coming to an end though?
Not soon. The other two movies (assuming it won't be delayed) still has four years to be completed.
Demon Slayer: Infinity Castle Part 2 would be released in 2027 while Demon Slayer: Infinity Castle Part 3 in 2029.

Oh wow! a branch of PETA that is actually responsible, competent and not crackpots!
Well, according 2020 Digital Civility Index (DCI) survey made by Microsoft, Indonesia ranked first for 'the most rude and disrespectful' in social media.
That's why nobody wanted to mess with them (unless for rage bait), not even PETA.
That and such movies as Alvin and the Chipmunks, The Smurfs, Woody Wookpeckers, The Smurfs 2, most Disney films these days and Smurfs, show that CGI characters over live-action doesn't always work. Especially movies based on video games. However movies such as Rampage, Sonic and Detective Pikachu has proven it can be done, but the last two games did had some clout and funding to back them up
I actually do enjoy Woody Wookpeckers movie.
But the story is really different from the comic/cartoon.
There are always things got sacrified when comic/cartoon adapted in the live action movie.
Chaclon!
I'm like Chaclon!
But without his power.
Or speed.
Just plain lazy.
