It's not a silly response.

"It's much easier not to switch" is just a peculiar way to spell "I don't care enough to switch" in this case.

There are automated tools that can transfer your playlists between streaming platforms, just for your own future reference.

Then you don't "don't want to be funding Joe Rogan at all".
