There's also the Softbank buys of equity at consistently higher and higher valuations that they themselves were creating.

"Generally speaking, Softbank’s model is to manipulate private capital markets as a way of drowning out competitors with cash. For instance, there were several ‘rounds’ of WeWork investment where Softbank was buying more shares at higher valuations. WeWork ostensibly became more valuable because Son said it was more valuable, and bought shares for higher prices. And since there was no public market for these shares, the pricing of the shares was totally arbitrary. WeWork then used this cash to underprice competitors in the co-working space market, hoping to be able to profit later once it had a strong market position in real estate subletting or ancillary businesses.
Engaging in such a strategy used to be illegal, and was known as predatory pricing. There are laws, like Robinson-Patman and the Clayton Act, which, if read properly and enforced, prohibit such conduct. The reason is very basic to capitalism. Capitalism works because companies that thrive take a bunch of inputs and create a product that is more valuable than the sum of its parts. That creates additional value, and in such a model companies have to compete by making better goods and services.
What predatory pricing does is to enable competition purely based on access to capital. Someone like Neumann, and Son’s entire model with his Vision Fund, is to take inputs, combine them into products worth less than their cost, and plug up the deficit through the capital markets in hopes of acquiring market power later or of just self-dealing so the losses are placed onto someone else."
