Accusing your paying customers to steal your stuff, and therefore not giving them updates (no think about it, what the hell else does he mean with "impossible to support", games aren't developed with DRM, DRM is enabled specifically for deployment, it is in fact easier to support DRM free games, purely from a development standpoint) is a great business tactic.
GOG should praise tinyBuild for treating their customers so well, and having such amazing views on DRM free storefronts.
