I would think many would be upset. That was before I found it however (luckily). I got in in late 2015 at .0001. Stock was already blown up but was still current at the time. Even so only put a small amount in, commensurate with the risk. They actually reported their best sales ever and 4 years of straight sales growth but just ran out of money.
There are some early investors that are still supporters though. And some of Dan's early people still help him out.
When oil prices crashed many solar and alt energy companies went out of business. WSTI almost did as well, and well it might still. But it has kicked around for a lot longer than some much bigger companies.
Everything I post is my own opinion and people should always do their own research and due diligence on any company they are looking at
