Why the quotes around "donates"? This doesn't seem like a white elephant, or a trojan horse. It's commendable that they gave it up rather than let it rot.
With a project of this size, scope, and adoption, I'd imagine the "acceptance" will be somewhat rubber stamped, and the process will focus on setting up the proper ASF development environment, review of existing code, etc.
I think a lot of people are looking for drama where none exists; ASF is just following the same procedures that EVERY project would be forced to go through.
I think that it's too late to really damage LibreOffice though. They have got a lot of support so far.
