Giving the benefit of the doubt too often is just saying, hey, that's ok, it's not important.
Well, it is important.
And ok - how DO you not notice a totally different tenor player. An obvious difference in sound and tone. How do you get a drummer totally wrong when the source tape clearly gives the correct name. How do you not go forward with a major project without making sure that all the rights have been properly assigned/granted?
These are not minor mistakes. A first-rate producer notices these things, researches them, and gets it right before taking the product to market.
And I'm not somebody squawking from the bleachers. I'm a paying customer. I've got a right to bitch about stuff like this, if only because not once has this been a mea culpa issued. Not once.
I believe the word that fits this guy is hubris?
