Yeah, you are right, and there are many projects that may not succeed from this acts due to get money quick attitude of some of these projects developers.
Again, one reason many developers stop their projects is,
Project running Out of Money (Bankruptcy).
The team behind the project reaches a point and becomes bankrupt. In most cases, this problem comes due to the aforementioned reasons. Some startups acquire loans from financial institutions to create a project, during the process of work, the team involved start disintegrating, and even others run away with the money meant for the project, remember the loan has to be paid, and what follows is the closure of the project.
