I respect if you wish to develop at a lower level, or use target only a specific platform. And I understand if you ran into issues with an open source library.

I respect if you wish to develop at a lower level, or use target only a specific platform. And I understand if you ran into issues with an open source library. I personally ran into multi-monitor issues with SFML in the past. Maybe it has been fixed now. But a different thing is to ask others to not use a project. Think that SDL is non-profit, ran by volunteer work mostly. In the past, cross-platform game development has been the target of many FUD campaigns so the tone is mostly out of frustration at this point. Then one point I didn't mention was licensing. Some open source projects may have licenses that are incompatible with a proprietary license. I think this was the case of SDL 1.x but SDL 2.0 uses the zlib license which is pretty compatible.
