I don't think I'm exaggerating.
Young adults (at least in germany) mainly stay in touch by using whatsapp or
skype; if you don't use it, it's really a HUGE loss.
Especially when it comes to contacts somewhere far away, these two provide a
way of doing almost real-life conversations, whereas you're basically limited
to email without them. Sure there are free software voip solutions, but there
are no people to talk to.
And yeah, of course you can listend to CDs, but that's almost like stoneage
nowadays.
People are used to being able to listen to every music they want all the
time, staying in contact with everybody conveniantly and so on...
If you really want to refuse non-free software, the combo "non-free
javascript + flash" breaks the web.
I would at least say that you can't use like 30 - 40 % of the internet this
way.
If you refuse to use SaaSS, things get ALOT worse.
Your digital life will be so different from the people around you - I don't
think you can count you in, when it comes to digital society.
