The whole "Trust me bro" thing comes from when they released their backpacks. They had issues with some of the zippers and people wanted to know what the warranty was. Linus said they didnt explicitly have one but that he would look after anyone with issues. When people got a bit rightly pissed about this, he got a bit defensive. "Trust me bro" sprung up as a meme out of that whole saga.
I honestly believe that Linus is a well intentioned dumbass. He likes his people and believes that everyone can just get along and that nobody would harass another employee seriously. He knows that the mistakes are just honest mistakes which is why he gets so defensive, take the whole "trust me bro" thing... I think it never occurred to him to fuck his customers over which is why he didnt handle it well.
He doesnt believe his employees need a union because I dont know about you but if I owned a company Id hope that my people felt looked after well enough that they didnt feel like they needed one either.
But that kind of attitude just doesnt work with so damn many people, he should have hired a full time HR manager YEARS ago, as well as the company lawyer on staff. He SHOULD NOT be doing the WAN show, or if he does it should be on a 5 minute tape delay with someone from legal and hr present.
The reason why so much bullshit corporate structure exists is to largely protect the company from itself.
