Actually, relicencing their code to ASL2 *DID* matter.
If they hadn't, LO would be LGPL3-only. I don't know how far LO has got with relicencing their code to MPL, but if it weren't for the Apache code drop, they wouldn't be able to - all the legacy Sun/Oracle code would be stuck on LGPL3.
And I know LO has ripped a lot of that code out, but it probably still makes up 80%-plus of shipping code.
