I'll stick with the ad/banner or removed functionality. I do in fact have a tendancy to register good software (especially if its from a small company/group) This is what keeps small groups going and helps to reduce the effects of monopolized software (uhm... m$)

Truth is, if your really that against the three... the only real solution is to register the product anyways. Most good shareware is not at all expensive, and if you use it more than once, chances are it's worth the $15 or so to register.

just my opinion
