This is not a news anymore IMO. Most exchanges are still doing this to pad their stat count to attract more traders on their platform. I'd be more surprised if exchanges are sticking to the clean and fair methods instead of cheating nowadays. Also, this happens right before they go public, so this might affect the stance of some investors looking to buy some of their shares. Either way, $6.5 million is already chump change to Coinbase so I guess they'll just shrug it off and call it a small hindrance.
