lol this has nothing with looking at it as if it's real. The show establishes itself in pretty real rules. Like one of the "points" of the show is how it's an accurate portrayal of Silicon Valley.
Like every show things have to make some sense. What I say about Richard would be the same as criticising a Game of Thrones character for a dumb decision. Of course it isn't real but within the show it's dumb and it breaks my suspension of disbelief.
Richard makes dumb decisions and with him at the helm Pied Piper makes no sense as a company.
If I sound like a tech blog is because well, this is a show about tech that deals in part with how start ups and tech companies work.
I'm not saying you're wrong on the point that Richard isn't a great CEO or that his firing makes sense-- that is a logical series of events. I'm saying I find it odd that you and others see that and root for Richard to just go away rather than rooting for him to change and evolve (which he's started to do). It'd make real-world sense at this point if he took a backseat forever, but as a narrative it'll be far more interesting to see Richard claw his way back and assert himself as a fitting leader despite his flaws.
Though, I've always liked Richard more than the average viewer I think. His being an ineffectual and inarticulate genius is precisely makes him an interesting character
