Yeah, and other businesses have the right to conclude that they'd rather use a full-featured open source web server than one that's crippled to create a market for the expensive proprietary version.

Of course, some people in this discussion seem to disagree - I've seen a lot of people acting as though it's somehow unfair to nginx for him to point this out to other potential nginx users or to switch to a different server rather thay paying up. It's like people here think the nginx developers have some right to bait people in with the open source version and then charge vast sums for basic features, and that anyone who isn't onboard with this scheme is greedy.
