It is NOT about Uber ordering fake Lyft rides to keep Lyft drivers off the street, as was alleged by Lyft last month.
It is about:
1. Uber using the Lyft service to get in touch with Lyft drivers, then trying to recruit them to be Uber drivers by presumably paying them more
2. Lyft trying to block Uber contractors from using Lyft, so that they cannot do (1)
3. Uber using burner phones and fake Lyft accounts to enable them to keep doing (1)
Also keep in mind the uproar here over the past year caused by Apple/Google/etc trying to increase profits by subverting the free market for tech worker salaries. Is the only difference that then it was collusion as opposed to an adversarial arms race? Or does the collective opinion depend on whether HN readers stand to benefit financially?
