I’m all on board with copyleft in general, but the “service provider loophole” just seems like anti-business sentiment. People using modified free software to provide services useful enough to pay for is a good thing.
Forcing someone to publish their own changes simply because they run a business always seems to me like violent coercion, using copyright as a stick; much moreso than forcing someone to release source for object code they are already releasing.
Free software is a tool. Using that tool to create a successful business isn’t cheating anyone out of anything.
The software is absolutely not free as in freedom if I have one set of rights with the ethernet cable unplugged and a different set of rights with the ethernet cable connected.
Stop the service provider hate and avoid the AGPL and AGPL software.
