Incorrect. For example, the relevant paragraph from the Google doc linked elsethread:
> any product or service that depends on AGPL-licensed code, or includes anything copied or derived from AGPL-licensed code, may be subject to the virality of the AGPL license. This viral effect requires that the complete corresponding source code of the product or service be released to the world under the AGPL license. This is triggered if the product or service can be accessed over a remote network interface, so it does not even require that the product or service is actually distributed.
What the OP is talking about is an aggregate, ie. two distinct pieces of software talking to each other over an interface, which is explicitly "non-viral", cf. AGPL v3 § 5.
That being said, the AGPL v3 is on the more arduous side of things, so it's easier to avoid them completely in a business context.
Sure, that seems like a reasonable interpretation to me.
However, I don’t have any specific recommendation against AGPL v3. Accounting is just one specific field where licensing virality could have particularly complex implications.
I don't think that's fair, Google is a monopoly with anticompetitive practices. Why is it a shocker that they would forbid AGPL? They want to have their fiefdoms while charging exorbitant rents. They can't compete fairly.
Also there are plenty of profitable software with AGPL licenses, some even get acquired by public companies [1].
Which could in turn "infect" your core offering to now become AGPL (and now you're having to release your core product IP to the public).
