Go tell the most competitive person you know to lose on purpose. Now, go tell any one of the 20 best drivers on the planet to lose on purpose. It's not an easy thing to do for the person telling them to do it nor the drivers themselves. It's against every fiber of your being as a racer to slow down and let someone by, and that's just in the vacuum of discussion. Now take Lando's last three races into context, put yourself in his shoes, and then pull over for your teammate. Did you do it? You did? Well, so did he. It's not PR perfection, but he's a human being that is willing to put his team first in the end. He's been mostly gracious about it, and even understands he lost the race off the line.
Contrast that with Max's antics and I just don't see how you can equivocate. Was it frustrating to watch real time? Yes. Was it also inevitable? Yes. History repeats itself quite often in F1.
