And that tactic is usually called dumping in international trade, it's one aspect of the VC-funding tech culture that I don't understand how hasn't been fought with regulation, it's incredibly anti-competitive since the price is artificially low and only sustained by losses through a massive amount of capital. It isn't healthy for the free market, it might lower prices for customers for the period while dumping makes sense and a competitor outlives others but it will inevitably lead to increased prices when a company finally engulfs a big enough marketshare to be safe. Predatory pricing is a ridiculous practice, killing a lot of innovation.
