Your comment history indicates that you like to be contrary and/or snarky, so I'm not replying to you, but for others reading this thread... there are actually good VCs out there (and yes, there are a lot of bad ones).

There are definitely investors who do this kind of thing to business partners, but they are usually non silicon valley, non tech investors (like a local car dealership owner who is investing in a restaurant). It is really rare among professional investors. It might happen again at the private equity level, where established businesses are being restructured, but there you could argue the value is not with the founders in all cases, or with management. I have little experience at that scale though.

In a startup, the founders, and their relationship with each other and the company, is probably the biggest asset. If an investor doesn't like the team, he just won't invest at all.
