the sad thing is that this has been out for 9 months. If Kite was looking for stats to help inform their product development they already got all the data they need.
they're also obscuring who this log data is being sent to by just posting JSON to an ec2 IP address (52.52.168.91). The server tries hard to not let you know it belongs to Kite. You know someone is ashamed of what they're doing when they take efforts to mask who's doing it.
or maybe any plain ip address... Or the more solid precaution may be to interpose on the sublime supplied network interface api and give people a log of which packages are accessing the network and what addresses.
