He's totally one of those people that's sort of attractive and has an authoritative voice so s lot of people have probably folded to him in arguments through his life. I don't like making generalizations like that about people but this isn't the first time he's acted like this. The one that really took the cake was the whole hardcore WoW raid debacle.

The TL;DR is, as well as not trying to really spend time on the parts that don't matter, he did some things that may or may not have been the right thing to do in the situation depending on your perspective. But whenever any of his guild mates or other viewers would criticize him he'd be so adamant that no, he didn't do anything wrong, he did exactly what he was supposed to do, etc. People would even explicitly tell him "hey, what's pissing us off now isn't that you did it, it's that you're so adamant you couldn't have possibly made a mistake, you're not willing to see our perspective. You're not willing to admit that maybe you could've been wrong. You're not willing to apologize." And still, his reaction to this was to triple down and just insist he didn't do anything wrong.

Like I literally even saw a clip of him talking to someone and he said "a lot of people think I'm being condescending when really I'm just providing context." And the guy talking to him points out "yeah, it's a problem that you think anyone disagreeing with you doesn't understand the situation, it's like you think they're stupid." It's like it short circuited his brain. It's like he'd never considered it.

So yeah, I have a pretty low opinion of him. But I also recognize that maybe all these clips are taken out of context, who knows. It's not like my opinion really matters. I don't work with him or know him. I don't care about streamers. I don't really watch them.

GPIOs are usually controlled by a single bit of a register anyway. Most likely you need to do something like:

// Set high
PORTB |= 1 << PINB5;
// Set low
PORTB &= ~(1 << PINB5);
