A product demo is not a manipulation. It is a persuasion that respects your audience and their autonomy. To be ethical, you need to use the following principles: honesty, transparency, and integrity. Honesty means that you do not lie, exaggerate, or omit important information about your product, its features, benefits, or limitations. Transparency means that you disclose any relevant facts, assumptions, or conditions that might affect your product's performance, price, or availability. Integrity means that you do not use deceptive, coercive, or unethical tactics to influence your audience's decision, such as false scarcity, fake testimonials, or hidden fees. Instead, you use logical, emotional, and ethical appeals to convince your audience that your product is the best solution for them.
