- that you then need a lawyer to negotiate, interpret and verify said contract and that is a *giant* barrier to entry for most people.
- you still have to rely on the co,pany to fix bugs, addd features instead of being able to depend on other users of the software.
Oh- and that the argument presented here can be reversed into “given that company X is providing such a flexible license, why don’t they just open source it and save everybody the lawyer fees?”
