Guilt-tripping customers into buying eco-friendly or charitable products feels manipulative to me, even when the cause is worthy. Last month I saw a brand shaming shoppers for not choosing their reusable bottle, implying they didn't care about ocean plastic. That pressure might boost short-term sales, but it erodes trust and turns ethical consumption into a moral test rather than a genuine choice. I'd argue such tactics are unethical because they exploit shame and anxiety, not honest information.
