My bigger concern is what it is gonna do to FOSS in general. While I'm primarily a Windows guy I use a lot of FOSS tools and this whole LibreOffice business, now with the developers abandoning ship, could really come back to bite FOSS companies in the butt. How? Because one of the ways to get serious revenue is to be bought out by a bigger company with the resources to put behind your project and who is gonna wanna buy a FOSS software company now? They will look at Oracle and say they didn't get the code (because libreOffice is quickly taking that) and they didn't get the people (because they all split) so what did they get for all that money? Office furniture?
I'm not sure I see that argument. It's perfectly possible to buy a non-FOSS company and drive away all the best talent, squander your customers' good will, lose the market position of your products though underinvestment and/or stupid strategies and generally drive the good name that you paid for into the dirt. In that case, you'd end up with nothing but office furniture too. When you buy a company, sure you have some assets both tangible and intangible. But also what you're really buying is a brand, a place in the market, some mindshare, a community, and good will. If you lose that (which is all too easy to do) then it doesn't matter if the company's products were closed or open, you're still equally screwed.
This is clearly another case of too many mad scientists, and not enough hunchbacks.
