at the end of the day you have to look at the actual information, and if there is some truth in it, then it would be illogical to dismiss it

sure, but the amount of nonsense (to avoid the b-word) i am willing to put up with depends on the amount of money i expect to make from the project. for unpaid work that amount is zero. if i am investing my free time and i allow you to benefit from it, you better be nice when you talk to me.

when i run a business then the information gained potentially makes my product sell better. for a volunteer project i may not care about popularity, so the information gained is not necessarily of any benefit.
