But you don't have to be part of the community to receive streaming updates, do you?
No you don't.
However, if you aren't part of the community and you're the one that happens to run into something brand new,
Then you could have helped the community to get new protection added.
Since you aren't part of the community, that new protection now doesn't help any one because some one from the community has to
run into what you decided not to share before the cure can be past along.
Hope that's clear. The only thing that's collected is what actually infected you in order to help every one.
