Really good points. Product is ultimately responsible for the user experience. The PM or head of product may not be a legal expert, but they better be an expert in knowing their users. Stakeholders signed off on the ToS or ToU. Each bears responsibility. However, Product is directly responsible for the outcome which is why a strong voice is needed - one that can say, "No Way!" when necessary. Of course, if the decision is made higher up the chain, then this just supports how deliberate the ToS change was - deliberate and worded exactly as it was intended. The wording was definitely unique enough that someone knew what was being asked for - legal expert or not - it was pretty clear.
