That's simply not true. Moreover, there are some people with pretty strong arguments who do not even THINK this should be considered a dark pattern.
However, it doesn't seem like you are interested in furthering this discussion. Would you have rather I not posted at all?
There are many YC companies listed on this Dark Patterns site, and their founders definitely frequent this form. So far everyone else has been completely mum.
Given that you are on YC's community web site, may I suggest using some tact?
