What if the conversation is negative? I have very little patience for halfbaked ads disguised as posts. Some companies just show what they are and sell, but too often these days it's a memey post-like advertisement which will be a negative the next conversation "ah, yes that company with those annoyingly fake ads, just like their [product]". But I do not rule out I'm the odd one out and the people deciding the tools to for upon people fall for those ads.
It doesn't matter if your personal interaction is negative if on the whole it's positive across a larger corpus of users. By and large this exposure tactic works more than not.
