It would maybe be useful to clarify what his mistake is ? >From what I understand Uwe mixes "contributing to open source project" and "using open source Qt for a closed project". In the former case, of course he's welcome to buy commercial licences for whatever project he'll be working on. In the latter case, the rational is (I guess) to prevent a company, say, to work with 20 developers for 3 years on an OSS Qt license, then switch to commercial when it's time to ship the product and the team is reduced to a core maintenance crew. That late switch is unfair to companies that are playing by the rule, but it's probably hard to police for the Qt company.
