Isn't this exactly what the last week of HBO's series Silicon Valley was about? Not getting valued too high because it may force your hand later?
It's not unique to tech stocks - it's very deep part of investor psychology.
E.g. in a romantic relationship, people being far more enthusiastic and more willing to invest in a partner with high perceived future potential earning and other value, than in a partner who's already clearly laid out all their cards.
At least, that's my take on it. I don't have any real experience here, so I could be totally off.
The reason I found it interesting is because I could see it actually happening. Of which, I'm sure it has.
