Wrt to the legal concerns with AGPL, they're not actually that it wouldn't provide any protection, but rather that it might offer the originally distributing entity too much power: legal power to declare all software used in the stack to produce a network request MUST be made source available. Basically, a ""contagious"" or copyleft license as GPLv3 intended, but even more viral than intended in the AGPL variant since it extends well beyond the source software. I have not seen any lawyer concerned with how Amazon would be able to bypass its protections, *because they're otherwise the same as GPLv3 and have already been tested.*
I think this poster created the legal theory themselves because they were aware of other legal concerns with the AGPL affecting the above scenario. I've read a lot of legalblogging about AGPL, and none bring up this as even a remote possibility, because unless you think GPLv3 case law is somehow irrelevant then you don't think AGPL will be simply bypassed.
One last thing: I'm surprised the poster was concerned about AGPL being untested, despite it using GPLv3, and not that FSL has only existed for 2 years and has 0 case law surrounding.
