It might seem like cheap shots if you have only seen short clips of it though.
BBT makes fun of stereotypes, in the way only outsiders can make fun of stereotypes: The jokes don't make sense, the writing seems to have no real compassion for the group that they are lampooning at all, and I've never actually seen people behave like the characters do.
Instead, SV makes sense for people in startups: It doesn't really spend most of its time making fun of how maladjusted startup workers are, like BBT does, but instead makes fun of the theater we all are surrounded by. By just turning the tech into star trek style technobabble, the show can focus on things that are relatable and real.
Take, for instance, a conversation they have, in an early episode of this year, about the problems of high valuations and down rounds. There were articles written about it that hit the very top of HN, because the conversation was so very real. The craziness you see in the GPs video? It seems deranged, but it's said by a character more than loosely based on Mark Cuban, and it's reflecting the values of the time when Cuban made his money! And his story covers a huge issue in entrepreneurship: Does the fact that you managed to get an amazing exit in one company really mean you will be any good later as a venture capitalist? Were you lucky or good?
If you take away all the laughs, the series tackles realistic problems all the time. So the series is not about easy laughs at the expense of people: It's a story about a culture, that happens to have laughs to make sure people that aren't interested in the culture are still entertained by it. Just like The Wire, it's not a documentary, but it sure seems to rhyme with reality.
