For hosting, I can see how that may be a useful clause. But for consulting or support? That's even worse than the usual terms for proprietary software. As far as I know, I can offer consulting services for Microsoft or Apple software without breaking any license. Similarly for software that builds upon proprietary software. As far as I know, this is commonly allowed without any additional license. Or am I missing something?
