That Time I Got Reincarnated as a Slime: Tensei shitara Slime datta Ken

Rimuru came, gave them power and didn't "want" (he as a person has no interest in it) anything in return from them.. he is doing it because he is a good guy.

Demon dude came, gave them power and supposedly didn't want anything in return. ("sounds" like a good guy)


Rimuru's underlings follow him without question - the exact same thing Gabiru is doing.

The difference is that Rimuru pretended to want something while the Demon is pretending to want nothing in return.
So basically, you are saying it's odd and fishy that someone would grant him power without wanting anything in return, but we know Rimuru is (inofficially) basically doing exactly that.

If Rimuru would have said " I'll help you, you don't need to compensate me" - it would've been the exact same situation right now. His underlings would've been extremely grateful and follow him blindly.
Gabiru has (supposedly) recieved power by being given a name too... so woudln't it be normal to be grateful just like Rimuru's underlings? (especially since some amount of "behavior change" happens whenever Rimuru names someone)


tl;DR:

It's weird to say that "power comes with a price" when Rimuru would be the best example of a random act of kindness. He helped the goblins because he wanted to help, not because he wanted to be their leader.

You are missing one mountain sized difference: Rimuru is right there, whereas nobody knows where the demon is and whom he's associating with. People only know he appears occasionally to grant a name to willing individuals, but nobody knows why and for what purpose. Rimuru's reasons can at least be somewhat seen: He's living with the folks and likes to address them with names, plus he wants them to get stronger to be able to defend themselves. He even participates, very much so, in defending them. For most people (or monsters) that would be enough to tell Rimuru is a friendly entity. The demon? Uhhuh, he could be a good guy because granting a name makes the name receiver stronger, or he could be plotting something. Nobody knows and they most certainly can't ask since they don't know where to find the demon dude.
