Until this week, I would have agreed with you 100%. But Wang Yilyu and Ratchanok Intanon both challenged Hawkeye. In the WS final, it was obviously a Hawkeye error. There is no telling whether the players will begin to doubt Hawkeye when it is not so obvious. For example, at 19-13 approximately in the XD SF, it is quite likely that Wang Yilyu only ceased protesting because they were so far ahead. His protests managed to get the fault call reversed, presumably because the umpire asked the service judge for a second opinion, then Wang challenged and was visibly incredulous about the Hawkeye decision. The graphics this week have probably made it clear to players that the system is either flawed or not automatic, or both. But as phihag points out, that doesn't mean they will necessarily stop trusting that the system is coming up with the correct call. We also still have no evidence that - even if someone is behind the curtain watching a video replay and picking a spot on the screen with a mouse - there have been any incorrect calls. There have only been occasional graphics that are thoroughly unconvincing. And despite the protests I cite, even Ratchanok and Wang stopped protesting almost immediately, and Rankireddy and Shetty didn't even flinch at that preposterous graphic so I believe your point about this being the 'best part' is still valid. I hope it remains so.
