Why care about politics?

Because if it's running well, you want to keep it that way. If it isn't, you want to fix it.

So, what can really be gained or lost? How important is it really? How risky is it to ignore?

Surely young people can at least care about the internet, how free and unrestricted it is?

There's also people besides yourself who can benefit (or suffer) from politics. Do you care about people besides yourself?
