I repeat that it's not the fault of Dark Souls itself that this shit happened. Miyazaki for instance deliberately adds various ways in all of his DS titles to "cheese" encounters and otherwise make them much easier for yourself. In interviews for Elden Ring he talks about how he always uses summons and makes Sorcery broken vs bosses on purpose for that reason.
That doesn't mean the design is unimpeachable or anything, but the repeatedly stated attitude of the director that is obviously present in the design of the games is counter to the "get good" culture.

And need stamina bars for basic movements
This behavior wouldn't be acceptable even in an activity where they're making money but they do this goofy shit for free.
