> technically I'm not selling software but a service so I don't have to do shit.
This is entirely untrue. If it were the case that 'I don't have to do shit', then why doesn't someone else do it too? Running a service takes a WHOLE LOT of work, and writing the software is, in many cases, the easy part.
We know this is true because whenever there is a conflict with a software license, the big cloud vendors just re-write it themselves.
The "comply with the license" part is the problem you're not seeing, using open source as SaaS is a loophole not a license feature.
An example being, I license something as open source which means if you don't pay for it (assuming there's an option for that), you are bound to follow the license I provided which means all further work has to be open source (the same license I used) and source has to be provided with the product. In an ideal world this would mean either:
1. We both get paid
2. We both contribute to open software which is available to anyone
But in our world it means, technically I'm not selling software but a service so I don't have to do shit. so the result (with scummy companies) is the following:
1. I don't get paid for software critical to your business
2. No one gets the benefit of the new product created despite my license
Hence, scum.
