Why are people so upset about mobile RTX 4XXX?

I don't understand, everybody seems to be saying the 4070 mobile has misleading performance, since it isn't equivalent to the desktop 4070. While true, this complaint doesn't make sense to me because as far as I can remember it's almost always been like that? I've owned 3 laptops, the 1060 Max-Q was nowhere near it's desktop counterpart, neither was the mobile 3070.

Now neither is the 4070, but it's at least closer in performance to its desktop counterpart. (proof and sources below.)

According to benchmarks (sources below) the mobile/desktop 4070 class cards are CLOSER in performance than the mobile/desktop 3070 class cards were respectively (by about 15%). Is there something I'm missing here?

1060 Max Q 6GB versus 1060 Desktop- 75% difference. 6GB-https://technical.city/en/video/GeForce-GTX-1060-6-GB-vs-GeForce-GTX-1060-Max-Q-6-GB

3070 Mobile versus 3070 Desktop- 55% difference. https://technical.city/en/video/GeForce-RTX-3070-mobile-vs-GeForce-RTX-3070

4070 Mobile versus 4070 Desktop- 37% difference. https://technical.city/en/video/GeForce-RTX-4070-vs-GeForce-RTX-4070-mobile

Again, I really feel like I'm missing something. When you can find great deals on 4070 laptops like the HP Victus one for under 900... why does everybody seem to want to complain so much?
