People will always complain - that doesn't mean the company aren't successful at what they're doing. I've been using nginx for a very long time and started when their docs were in russian and hardly translated into english - I applaud them for doing that step and creating nginx plus - I suspect that in the future I will need/want to pay them a license fee. If my company is creating lot of value and part of that value is enabled by software I use - I think it's only natural that I pay back some of the proceeds to support the software I use, especially if in the process I'm getting more features and better support.
