Is Nick Stakenburg Bullying His Open-Source 'Competitor'

This is obviously a scare tactic used by a vendor to frighten a 'competitor' who is encroachinig on his sales. Nick (the vendor) is jarred by the fact that someone has released a comparable (better?) product that his and it is free. It behaves somewhat the same, so obviously it was copied... This is a serious issue, we can't let companies push around open-source with threats like this.
