I wouldn't really look to Joshy's videos for information, or any non-Japanese speaker's videos for that matter. They can provide a glimpse, yes, but they'll never be as accurate as someone who can actually read what they're doing.
I like Joshy for entertainment value. That's it. To me he's like an average person's reaction to a game, not some source of information. His is like watching a sort of first look review while LinandKo are more like an actual "guide" (in quotes only because their play style isn't 100% informative and they show themselves actually enjoying it instead of spending all their time translating/giving information).
And I imagine the constant pestering and for all we could know, the constant harassment, he just doesn't feel as into the game. Even Lin sounds a little strained with her patience at times. A lot of her recent videos urge people to watch the full video before asking questions. Getting the same questions over and over and over and over again, after you answer them constantly, can get old very fast. Lin just so happens to be very nice and polite about it, but at the same time I don't think that means she should have to deal with it in the first place.
A lot of people are entitled and rude, especially on Youtube.
