Despite having been a lawyer (with only limited work in intellectual property), I've never understood quite how the Open Source license works. For example, I don't get how Android can be based on a Linux core and nonetheless have closed source aspects.
In this paranoid state, I further wonder whether Nokia can use its retained programmers to develop MeeGo-oriented software, and then kill it with copyrights/patents so that critical parts of a future MeeGo OS would be crippled by making them proprietary, unused, and unusable.*
*I've long wondered whether Microsoft had a secret agreement with NetManage (and thereby with its successor companies) to keep EccoPro out of development. EccoPro is a very powerful PIM (with many unusual capabilities, such that Personal Information Manager doesn't really encompass all it can do) that still has a following, even though it's had no development since 1997. NetManage acquired EccoPro in mid-1997 and immediately stopped all further development of it. Numerous people tried to buy EccoPro from NetManage, even as recently as the last couple years, but NetManage wouldn't sell it or open the code, even though it gets no income from the product. The only beneficiaries of NetManage's refusal that I can think of are other PIM vendors, like Microsoft, which sells its much-inferior Outlook.
