When I opt out (or never opted in) and am still sent promotional material, it is an explicit message that the company disrespects me. Responding to that with shrug is layering more disrespect on top of it. Disrespect for users is a cardinal sin, and quickly reaches unforgivable levels if left unchecked. It is simply incorrect that this is an issue of bias against Mozilla. Other companies behaving worse doesn't make it acceptable - in fact, Mozilla's image of being "better" makes these kinds of infractions worse.
I'd argue they're merging into the same thing for certain products with frequent releases. Things like VS code get free marketing every month with their release announcements hitting the front page of HN, reddit and the like.
