My point is that allowing alternatives for a price removes the incentive to fix the free somution for everyone who can afford that price.

In that case please stop driving (go fix public transit), eating at restaurants (go fix soup kitchens), using Lyft (go fix cabs), etc...

(The point is: the people providing alternatives are under no obligation to fix anything. Isn't HN all about disrupting bad models?)

You could say that YC is.. HN is just a tech news/discussion site. If anything it's all about (comparatively) respectful discourse.
