Could you please keep your statements truthful. There is no proof that Kalanick or Uber stole anything from Waymo. There is an ongoing and unresolved court case to determine that. It's only appropriate to make such a statement, if it's proven that Uber stole anything. This is HN not reddit.
Thus far, all we know is that Levandowsky alledgedly took files as leverage to make sure Google paid him the bonuses Google was late on, but he was expressively forbidden by Kalanick from bringing any of those files to Uber. All the discovery performed so far has turned up zero evidence that any files from Waymo ended up at Uber.
It's not uncommon for legacy companies to sue newer, more nimble and more promising companies over IP issues when they lose star performers. It also happened to Google when Paypal sued them for trade secret theft when promising senior talent left Paypal to join Google Wallet:
It's perfectly okay to recruit promising talent from other companies with better offers so long as the recruiting company keeps everything kosher via due diligence that ensures the talent does not bring intellectual property from the previous employer to the new company. All evidence made public thus far suggests the Uber did its due diligence here and made sure nothing belonging to Waymo made its way to Uber.
