The AGPL is great, even for business. I make a living from AGPL software. Lots of people generally don't like it, because AGPL was not written to please the largest number of developers, but rather to protect the basic software freedoms of end-users. In a sense, the AGPL guarantees more freedoms, is more free, than other licenses such as MIT/BSD for end-users. But depends on the point of view.

Many developers don’t like to have their freedom to steal to be restricted by such strong terms as those imposed by the AGPL. And that’s a good thing for you, my fellow maintainers. It’s also a great thing for you, dear end-users.
