Hell yeah. Don't threaten me with a good time.

Philosophically I don't disagree, but in reality the likely effect of a rule like this would be even greater empowerment to the incumbents, which are mostly huge tech companies. Maybe it doesn't matter since the vast majority of startups don't mind be equally abusive, and often have an exit strategy in mind of getting acquired by huge tech, so hell it might even be a net positive in some ways. However, this would also have the net effect of ensuring that ethical startups seeking to disrupt gross entrenched practices would be dead before they can even start. Given the direciton the tech cos have already long demonstrated they want to go, that strikes me as a much bigger evil than not having access to customer support
