Anyone who thinks the file headers are an issue, and that merely changing them does anything to the license, has a poor understanding.
Take a look at the README. The file headers tell you which files are IBM contributions, versus pre-existing OpenOffice files. And read some other, more perceptive comments on this same topic.
In any case, you seem to misunderstand what Apache projects do. We don't just take code, slap a new license header on things, hold our nose and toss it over the wall for public consumption. That is not how we operate. We're not the money launderers of the open source world. We do thorough reviews or we don't release at all. There is no Apache-lite release. I sense that you wish this were not the case, but it is.
And note that there is absolutely no issue for project members to touch the code. They already have. Indeed, with the Oracle SGA it took 6 months to clean up all the headers, and all along we were all working on the code base. So that is non-issue, more FUD.
