The gMove app exports email, contacts and calendar information stored in Microsoft (MSFT) Outlook to Google’s online services. LimitNone apparently developed it with Google’s help and the understanding that the company had no intention of offering a competing product. But at some point, Google changed its mind. And it built Google Email Uploader–allegedly using LimitNone’s trade secrets. “Google claims its core philosophy is ‘Don’t be evil’ but, simply put, they invited us to work with them, to trust them–and then stole our technology,” said LimitNone’s CEO, Ray Glassmann.

A harsh accusation. And likely a tough one to prove. LimitNone never bothered to patent gMove. And beyond that, it’s hard to believe Google is so lacking in engineering resources and expertise that it would purloin an email migration tool.
