It's not that Satoshi makes that many demands. But I think lantz's writing for the RP sometimes clearly tried to force the narration along in a certain direction without giving others a fair chance to do anything.
(I recall something of an outrage over the Angra Mainyu cop out in Forest's complex a while ago.)
Like Gray has in regard to the way he wanted to play Grim, lantz's writing for some characters has come off as somewhat forceful on occasion.
And even if Satoshi hasn't been that demanding (mostly liking to take charge when he doesn't need to), future Rin has definitely seemed demanding, and been disrespectful in that way.
