That's completely absurd. Pre-check does not always work and does not cover family members. Pre-check lines can also be longer at some airports with so many elites (like UA at SFO). With Clear there is never a line and you cut right to the front of the conveyor belt.
Personally I rarely use SJC as it is not convenient for me, but nice to know that I will not have to worry about a TSA line (last time I think it was 20m there). Now all we need is OAK to complete the trifecta though to be fair I rarely have to wait there either.
