1. Eich's action had no complexity or other goals. Eich supported something where the SINGULAR purpose was to strip a class of people of a right they had only recently acquired. There was no complexity to it, no shades, it wasn't as part of his duties, it wasn't as part of a team, it wasn't as something he was forced into, it wasn't something he regretted. 2. Mozilla isn't Dropbox 3. CEO isn't Board Member.
