This discussion is about the Qt binding library for Go, not Qt. The existing Qt binding they're talking about is LGPL and cannot be bound dynamically, and therefore makes the distribution of proprietary software impossible even with a full Qt license. This new binding alleviates this problem because it's MIT licensed. You still need to adhere to Qt's licensing, i.e., buy a commercial Qt license or bind Qt dynamically like most people do. Qt has a commercial and a LGPL licensed version.
