Lets say you develop a hobby for making furniture. You start developing Tables. You read a DIY book and start making stuff. In the meanwhile, you make mistakes, you don't put as many nails where there are necessary. You put more gum than what is necessary. Your finished product is definitely a table, but you've made is so badly it could hardly last for a couple of years.

A carpenter down the street comes down to you shop and gives a detailed critique of what he thinks is wrong with your table.

Now you both go and try to sell your story, You have a table and he just has a critique. The user comes and sees your table and listens to his critique. He decides something that exists is better that just talk. Remember the user is seeing the table only, he didn't see you making it. He decides to go with your table despite the carpenters critique.

He orders 50 more tables from you to be made based on what you showed it to him.

Now the professional carpenter can argue about how bad and how many technical deficiencies exist in your tables. But you know what, the user won't even understand that language.

Because, Shipping is a feature. And the one's who ship almost always win. Sometimes even if they ship crap. That is what is happening here.
