You seem to be trying to reduce the vendor-lockin issue to a binary "locked" or "not locked," but Idon't think that's a productive or realistic way to think about it. It's really more of a spectrum, and I prefer to think about it as "options" rather than "are we locked." You definitely have a lot more options if you go with Nginx and the project turns evil than you would if you went with some proprietary offering.
