No, you’re forgetting the fact that when I bought it, I didn’t know what I’ll be getting in the future. I lucked out with Factorio, but it could happen that the devs just stopped working on it, I didn’t know at the time.

That's the risk you paid for. My criticism is price increase after full launch. If early access game goes up in price when it fully releases that is a different thing.

Who do you think sets the price, if not the publisher?

The publisher sets the price. They put a game on sale to make more money. I buy the game on sale. I get the game as the reward. The publisher gets money they wouldn't have otherwise.

And yet, it’s not the publishers complaining about it online.

I'm a random person who has no reputation to defend. I could just as easily start over online and nothing would hurt me. The publisher has a reputation to keep. They need to keep making money. Other then that, complaining is the way to for the consumer to get thoughts out about practices. I don't like a game going up in price due to "inflation" and a game never going on sale therefor I will communicate that.
