At the time of my comment, there are dozens of comments disagreeing with Paul and only 2 agreeing.
And this goes to show you - most people will not accept an advice from someone who knows better. If a conclusion must be reached, it must be reached under your own power, and at your own speed. This just can't be helped, it seems. Or can it?
Another possible conclusion, however, is that the world has changed in the years since last time Paul was actually doing this, and people with current experience are pointing out that his advice in this case is actually out of date.
Paul is drawing his conclusion from seeing through hundreds of startups and still being involved in YC to this day. His opponents draw their conclusion mostly from seeing through zero startups, that is being in the middle of their first. Then a much smaller number of people have between 1 and 3. This vast discrepancy in experience is strike one.
Strike two is that pretty much everyone has an unhealthy attachments both to their own creations and to their own "identity". It gets even worse when the two are combined. Even Paul himself, one of few wise men of our times, gets very defensive when his creations are under fire. It's just how people are. Yet in this case Paul is a more objective observer, he doesn't have a stake in the game of naming your company.
The insidious part of strike two is that it's nearly impossible to recognize while you're in the grip of it. It's like being drunk - most people who are severely drunk think they are "ok to drive". They aren't.
Accepting advice takes one of the two: either blind deference to authority, or wisdom to recognize the limits of your own understanding and selective deference to those who could know better. Not perfect, mind you, just better. Alas, wisdom is hard to come by, and blind deference has significant downsides. And so it goes. Most useful advice goes unheeded.
