Truelly, powerfull projects don't use bounty at all.
Every project needs promotion, even the best one. Bounty is good for promotion and help to pay attention of investors to the project.
many projects use the bounty company as hidden advertising to attract attention, but the expected result is not always obtained, unfortunately.
I dont see anything wrong with that, on the contrary, I welcome projects that give out a few free tokens to those users who cannot afford to buy and dream of getting the desired token. Do good!)
