@jhimi6 Hey! I think I mentioned this before too, I had better visions for it and unfortunately my own incompetence (even after finishing it) didn’t work out in my favour. I see only flaws in it, and would prefer not having it anywhere so I have taken it down. I wish I could do better with the story, because it looked better in my head.
To your second point, it might be because writers here don’t get any readers on ongoing works anymore. To be honest, there were so many instances when I too felt only a couple readers were still interested or reading it, so after I completed it (for my satisfaction of finishing something and for them to finish reading), I took it down.
Lots of writers do this on top of all their other personal life responsibilities. Maybe it you feel lots of writers take their books down before you read them, it could be helpful if readers just dropped a small word of encouragement on ongoing works so writers who might be second guessing themselves have that motivation to pull through and complete it.
