The following questions aren't meant to be antagonistic, but your PR has just taken a hit, and the specific claim made in this post about the LOI isn't a small one. Let's clear it up.

There was good discussion of this on a prior HN thread when @sama posted that blog piece. If I can dig it up I'll add it here.

Is Sam Altman involved with TechStars? If not, why is his name being evoked? It's great that you agree with him, but OP is saying that at least in his case, this point of view was not honored.

One issue that is relevant to us given our fixed class sizes is getting a definitive answer from a offer though as quickly as we can so that we know if should move down the list and give an offer to the next team instead. Having 10 offers out and finding out that only 8 want to accept would mean we have are giving out 2 offers potentially much later than the others. Purely as a practical timing matter we hope to give out a set of offers and have everyone accept or dismiss them pretty quickly so we know who the class will be.

I understand, but this is simply the universal rationale behind pressure tactics. Your desire for quick resolution is understandable, but the specific claim made in the post needs to be addressed.
