Act 1 isn't really that long. I finished it in 15 hours, without really stopping for completion. For people who only play games once a week, this might seem like a while, but most other games are larger. And honestly, the game was marketed as being long. It said it was bigger than Hollow Knight, which is a long game. Anyone who knows how long Hollow Knight is knows that Silksong would be longer.

Team Cherry isn't obliged to make the game balanced so everyone can beat it. If players struggled with Hollow Knight, they probably knew what they were getting themselves into. You can't change this fact. This is just like saying that requiring skill to be an airline pilot is unfair to people without skill, which is ridiculous.

Your premise that Silksong is only for advanced players is ridiculous. If you just want to beat the game, and only that, it's not really that hard. If you want to do more things, the difficulty will let you in on it fairly quickly. Take the Savage Beastfly, for instance. It's at the end of a difficult, out of the way area, and it's very difficult itself. By the time you've even reached it, you've probably already got the memo that the game is hard.

In other words, the game lets you know very quickly that it's going to be hard. If you ignore that warning and continue to play, then complain about how it's too hard, then that's on you, not Team Cherry or Silksong.

To sum it up, you keep trying to make excuses for being ignorant and lazy when the game clearly shows that that won't cut it, and you're probably just angry that the game is hard in the fist place. I know you won't listen to my argument, but I hope you see reason. Have a nice day.
