Yes I am sure some people would sue over this huge inconvenience. We have become a soft litigious society.
For some folks, those bad knees, folks at risk for SVT, might be more than an inconvenience. Lack of legroom is why I don’t fly anymore. Period.
It’s not so much the inconvenience as the rude, arrogant attitude on the part of Delta.
What would you do if they treated you like that?
