I am not disagreeing that in this specific case that the licence structure might lead to unhappy arithmetic. I do however stand by my original point that syslog support is an excellent cleavage point to segment the customer base.
I'm slightly less happy about the HTTP live streaming being in the Plus package, though. I've been playing around a lot with a media app using HLS and I can't even trial using nginx for it - not that I'd be too happy paying $1300 a year since I don't have a single user yet. I can see how they are trying to get money out of the big streaming companies, but it's not too friendly to the little guy.
Probably because you are not a systems engineer. Did you see what it resulted in here? Many of the people who have systems large enough to hit these issues will just work around it using the ramfs approach or by just dumping nginx. Either way you have a skilled engineer disappointed in your product.
Don't differentiate FOSS with paid on something that simple, especially something that has been supported by apache for almost a decade.
