Take this analysis with a grain of salt. I feel competent to say this because I created the LO credits page, that Bruce uses as a source of data. :-).
First of all, the LO credits is based on actual code changes contributed in their name, taken from the git. The initial apache list of committers seems nothing more than a list of people being interested in the project, there are forum administrators and other non-coders in there. I see also a number of employees from Oracle who have previously been involved in non-coding positions, such as a "community manager."
Don't misunderstand me, I wish the Apache project good luck and it's great to have people signed up that want to support it. A healthy community of non-coders is certainly crucial. But attempting to compare these numbers is futile and dangerous.
