Notion Ink makes the Adam Tablet, and developer Jesse Vincent is accusing the company of taking his open source K-9 Mail code without giving him credit.
According to the Apache 2 license that K-9 Mail is released under, Notion Ink is required to credit all copyrighted, patented, trademarked and attributed work.
“It’s not known how the oversight — if that’s all it was — will affect the operation of Notion Ink,” Electronista reported.
