Funny to see him in that video, with him getting begged by his viewers to cover the CSAM scanning controversy on every video for weeks - but he ignored it. Wonder why.
I don't think there's anything nefarious going on. MKBHD is a "cool tech bro", and he knows that, and that is what he excels in. He isn't particularly great at talking about more niche, meta topics, until they hit the mainstream. His recent Right to Repair video shows this, and it took him YEARS to make that video - but it's also one of the best.
FWIW, he does talk about CSAM and is definitely aware of its pitfalls on his podcast, so it's not like he's blindly banging the drums.
In which episode(s) did he talk about it? I checked 2 or 3 episodes around that time and it did not come up. We are talking about the Waveform podcast, right?
Besides that, I'm sure his reach on Social Media & Youtube is quite a bit larger than on his podcast. And I guess, the reason he had those comments under his videos was, because those people don't listen to his podcast either.
