Google will drop part of the Chrome licence after concerns about the licence were aired.
The key issue is the licences section about intellectual property - not everyone wants to surrender their intellectual property rights - in fact some people can't due to the terms that they work under.
There are also concerns about how much memory is used. It uses more memory than Firefox 3.01, but roughly the same amount of processor time. Like Internext Explorer 8, Chrome's designed for upcoming hardware - not everybody has that or can afford it.
