Generally I would agree with your statement but you are misrepresenting the facts.
Eve royally messed up with the payment processing and had a large chunk of funds withheld without doing the proper amount of due diligence.
To add fuel more fuel to the fire, after their liquid balances went to zero they thought the best way out was to use new buyers to pay for the components of previous batches, essentially running the business at a rolling negative, they would never be able to claw back into the positive because their profit margins are too thin.
Simple fact is Eve failed to build any contingency into their price and made a poor judgement by spending so much of their money on fancy packaging etc. All of the packaging and shipping bubble wrap etc probably came to $25+ which is ridiculous.
Also they failed to properly plan a burn rate and thus ran out of money before securing further investment. They have basically spent the last year looking for investment and still have yet to receive funds.
Both of these are basics of business. sell devices at a reasonable profit (better to overprice initially and then put the devices on sale then to crash an burn by underpricing and not making any money). Don’t run out of money (always be looking for investment at least 6 months before you run out of money).
Unfortunately, both these problems are down to Eve poor planning/foresight not due to any third parties.
So yes buying products has risks, but you would not expect the company to run at a negative to the point that they have essentially been bankrupt for nearly a year and thus cant offer refund to the people they’ve screwed over. For most people the price of a V is a significant amount of money and it is sadly ironic that a company that aims to flip the pyramid should have looked at how those ‘evil’ companies do basic business.
