I think it is hazardous to count the number of committers and PMC members that are part of a project that is built at the Apache Software Foundation. It is helpful to keep track of these things to make sure that the project keeps its independence, and is not unduly influenced by the interest of any one company or organization. Committers and PMC members earn their position based on their own efforts as individuals. They don't represent their employers.
The current Apache Lucene PMC chair just happens to work for Amazon today. A number of folks that used to work for Elastic now work at Amazon. But over-focusing on that, and keeping careful track of what company contributes how much to ASF projects, is bad for community health in my personal opinion.

Companies should also be respectful of the communities that produce and maintain software, including understanding the philosophy and governance that communities have adopted. For the Apache Software Foundation, this is being mindful to not unduly influence the project, such as to try to control it through employing a majority of the people who work on the project, or otherwise weaken the independence and autonomy for the community that builds and maintains the software.

I've seen situations in the past where companies employ an open-source marketing strategy that ends up encouraging unhelpful activity in open source communities. This can also happen when companies measure the performance of a software developer based on metrics such as "number of patches accepted in an open source project." This kind of thing is generally unwelcome in open source software communities. See this thread on HN [3] on the Linux kernel development list, TL;DR - "Please don't waste maintainers' time on your KPI grabbing patches."
