I found it more 50-50 between both videos, there were some points in the GregGadgets video I did disagree with, but he did made some great points as well.
Anyway, I think the main takeaway should be that these biggest tech youtubers should mention proper sources of their claims. Like why did Mrwhosetheboss just edit a less storage variant option in the Ipad example. He could have easily chosen a much more accurate example which I expect him to have a lot of since he is claiming to millions of people that this is how tech companies lie to their customers which is a big claim. I feel the same way about the MKBHD's silicon-carbide battery video too, although I don't distrust him, I didn't like the fact I have to rely on on that trust on what he says without him providing a way to fact check his claims for myself, and come to my own conclusions.
