what do you think of people who use linux but use non-linux related stuff as their wallpaper??

like for example,, one time i was browsing through some neofetch screenshots and i found out that a lot of them have anime or furry stuff as their wallpaper or profile picture,, but they use linux. hmm or maybe they even have proprietary videogame images!! i used to think that was bad but now i realize that even if you have proprietary stuff as images like,, furry fanart of some proprietary videogame, it's like just a picture, a jpeg. but still,, younger me would've freaked out by the idea of having proprietary files, but i still enjoy linux. what do you think?? please
