a) This software is provided ‘as-is’, and as the author, you are not liable for damages if someone uses your library for something crazy.
b) Anyone can freely use it, for any purpose, with following restrictions:
1. “If you use this software in a product, an acknowledgement in the product documentation would be appreciated but is not required.”. They decided not to acknowledge the use of your library. You explicitly said this is OK.
2. Altered source code -> probably not.. it’s a web socket handling library.
3. This notice may not be removed. They have probably not removed it from their source code, given they distribute a binary.
