Gah, you're right. Their paid services and limits seem to be related to their SAS offerings.

Your passwords are stored on their server. You'd have to compile and run your own server, which is more expensive than the $1/month they're asking for.

So you’re paying for the service they offer: a hosted version. You do so because it’s cheaper than hosting your own. There’s no conflict at all with any open source ethic.

Yes, that's exactly what I was saying.

For people like me that already rent a VPS for their mail and website the marginal cost is $0 except for the time it would take for me to perform the installation and setup.

If the system is good and stable then the "cost" of the time that I would spend installing it on my server would be close to $0 when divided over the amount of time I use the software in the future.

I think another plus of buying their service is your supporting development of the software and saving yourself time, while a critical piece of your security software remains open source.
