Again, there’s literally no reason for you to believe that this price increase somehow means you’ll never have to pay for dlc. Have you never heard of Factorio?
And for the record, like with your Minecraft example, I’m not against devs charging less for Early Access versions, alphas, betas, etc, and charging more for the finished product when it fully launches. That’s a very common practice, in fact it’s the standard.
That’s very different than deciding to increase the price arbitrarily in the middle of developing an early access title that’s been in development for 5 years, and isn’t releasing officially yet.
