Skype keeps starting at startup without my permission. I don't want it to start minimised, there's already a solution for that, I want it not to start. But there isn't a single setting in Skype's options, and Skype is not in my startup applications.
EDIT — as requested, a screenshot of the "session" tab in my Session & Startup settings:
And the weird output of that "grep -lir 'Skype' ~/.cache" command, giving me something about Kingsoft Office:
