Hi Kamil,
Not really. They could have got their install medium from an event, a conference, a friend or a colleague, university or college... Maybe they didn't even install the system themselves. Often someone with some knowledge of Linux install it in their relatives/friends/partners/colleagues/classmates laptop or computer. Also, a person may want to try other systems or maybe they didn't know about Spins and Labs and now they want to give them a go. Maybe they made their install medium in another system and now what? Asking someone to borrow them 15 minutes to make another install medium?
I always thought it was a bit strange that Media Writer is not installed by default.
Kind regards,
Silvia
