The issue with SX was never simply about 'credit'. TX are free to use Atmosphere code. In fact, TX are free to keep selling it, as GPL allows this. All TX have to do to make SX compliant with GPL is release the source code, since they are using open source GPL'ed Atmosphere code. That's it.
This is not an unreasonable request.
Don't get me wrong, I get that and I 100% agree with you. What grinds my gears is the Toxicity coming from SciresM and his Twitter page (take a look). Most of his posts are intended to bash TX and cause toxicity and I get that, they took "his" work and they didn't give credit. But Jesus tap dancing Christ, it's been over two months by now FFS. The whole toxicity is coming from him and his petty attempts of bashing and cracking the SX OS when in reality he could've spent that time to finish his so called "CFW" already.
