I think we all can look back at some of the initial claims from Boeing on the 787, that they subsequantly toned down, about how the circ system on the 787 was so much better at removing toxic chemicals from the cabin, virtually acknowledging the issue.
They toned it down after reporters starting asking if they were going to retrofit their existing aircraft with the system.
Huh? You have a gripe with the 787?
