This is a pretty hypocrite thread. The guy is successful, has a lot of money. He starts a company thinking that because he has the best product he is going to win the market. Things don't go as planned. Blame the VC and competitors for it.
First, his company was VC founded. He poured 10M in the company that's very close to having raised 10M
Second, you dont go out of business because someone created a competing offers
Last, he his a successful guy, it is difficult to go openly on Twitter and says "I failed because we were not good enough" it is easier to follow the trend of our time saying that VC is evil.
