Ask HN: MVP vs. Landing page

I have lately noticed that a lot of people confuse or claim their landing page as MVP. There are websites like quickMVP that just make a landing page but call it MVP. I am curious if that is the case. Doesn't MVP refer to a hacked prototype which might not look good but does everything that the real product would do? While landing page is just single page webapp to market your idea? Please share your thoughts on this.
