FWIW, I’m pretty sure Facebook also uses mongodb heavily (or at least through its acquisition of parse) I don’t know if they have a commercial license or not, but they aren’t strangers to the AGPL
MongoDB also makes their interpretation of the AGPL pretty well known - unfortunately it’s at odds with established interpretation of the normal GPL.
Requiring GPL/AGPL software as a dependency even if you don’t link to it, but instead talk to it over the network does not mean you haven’t developed a derivative work in terms of the letter and spirit of the license. This is in-part why I steer 100% clear of MongoDB, there’s nothing stopping them from changing their view on the license and deciding to pursue legal action against people who use it in non-AGPL compatible manners down the road.
