Verified step by step guidance

1. Step 1: Understand the context of the problem, which involves consumer behavior related to commenting about a brand on Twitter despite having a high willingness to pay for its products.
2. Step 2: Recognize that willingness to pay reflects how much consumers value the product, but it does not necessarily translate into public engagement or sharing opinions on social media.
3. Step 3: Analyze the possible reasons that might prevent consumers from commenting, such as privacy concerns, which relate to the fear of personal data exposure when interacting publicly online.
4. Step 4: Evaluate other options: low consumer surplus means consumers gain little extra benefit, which contradicts high willingness to pay; high elasticity of demand relates to sensitivity to price changes, not commenting behavior; perfect information about competing brands affects choice but not willingness to comment.
5. Step 5: Conclude that concerns about privacy and personal data exposure best explain why consumers might refrain from commenting extensively, even if they value the product highly.
