Yes, this is my attitude as well. A lot of the work I've done has required the use of proprietary tools; you might not be getting paid to improve the tool, but you are (presumably...) getting paid to produce a product, and if the tool is getting in your way somehow then you need to do something about it! Even if you don't bother to report usability issues or suggest improvements or what have you, if you encounter a bug that's blocking progress, sitting on your hands isn't going to help anybody. (Of course, reporting it might not do much either ;) - but that's something you need to find out on a vendor-by-vendor basis. Some are responsive.)
