I think OPs point is that commercial vendors will now stop providing the source code, which deprecates the overall quality (I don&#x27;t like working with code I don&#x27;t have the source code to. Once you find a bug, this all blows up on you).<p>It think it is a big win that proprietary software needs to ship source code with them in order to sell the library. Just because there is source code doesn&#x27;t mean, it is open source or free software. It can still have the same licenses (not share the source&#x2F;bin, etc) but source code that is visible (even proprietary) is better then a binary.<p>After all, not all libraries are OS and those that aren&#x27;t would suffer from that change (although marketing guys would probably argue differently).
