The actual problem is, I do not even think bounties are useful for project. There are thousands of projects on social media shared by those people. So how can one be seen better than other? Bounties should turn to 'Social mining' so people should compete with each other to create useful content. I really like the social mining concept to be honest.
No business is going to pay for something they do not consider valuable, it is obvious that if they are willing to give away so many of their coins they are doing it because they know how valuable it can be to have a successful bounty campaign, but we have reached a point of saturation in which all the coins are doing the same and are competing for a very small amount of money compared to what they could get during the bull market of 2017.
