Google is making the source code for its Android platform freely available.
LiMo and Symbian, which also is going open source, each use different licences, but both include obligations for people who change their code to share their changes, Shikiar said.
Shikiar also criticised Google because he said the search giant hasn't created any sort of governance model for the Open Handset Alliance and doesn't publicly publish the group's membership agreement. A governance model spells out for participating companies exactly how their intellectual property can be used by other members. Without it, members might be reluctant to contribute, he said.
The OHA did not reply to questions recently posed regarding its choice of licence and its governance model. Google was also not immediately able to respond to similar questions.
