What I had in mind was more a long the lines that windows/Mac OS isn't transparent and the consumer has limited control over what it's doing and how to implement things. Furthermore their official app stores are a walled garden of sorts.

Consumers/developers have a good deal of freedom on these platforms and with that comes breakage in various forms. Malware, instability, etc. And to deal with that you have repair shops/programs. System resets, fresh installs etc. Maintenance becomes a responsiblity of the consumer.

Like I said, the lines can move based on context. Moving the needle further towards freedom for developers/consumers gets you *nix systems - which is harder for your average consumer to maintain/use. Moving away gets you iphones/consoles, etc which "just work" and flaws in software/hardware handled by the manufacturer.
