I think you may have misunderstood the OP and actually agree with him. He's saying that AAA studios (sometimes) spend more money to produce lower quality products, and that claims from some AAA studio devs that you shouldn't use BG3 as a new standard are just them trying to excuse their own mediocre offerings.

Skyrim and Fallout 4 were made with about 100 people each. Witcher 3 had about 250 developers, and Cyberpunk 2077 closer to 500. Larian's Baldur's Gate 3 team has over 400 people, 10 times the developers they had for Divinity: Original Sin (1).

So how do you describe a 400 person team? Mid-level?

I mean there are companies which can be described as having much more resources yet performing much worse.
