Making money off open source / free software is okay, it's completely legal, what is not legal is breaking the license you agreed to when using software, which aparently SXOS does.
Wow your facts are waaaaay off.
For example, GPL2
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
I suggest you do some research before making such blatantly ignorant and false statements.
