This line of reasoning begs the definition of "crapware," and the #1 response would be "stuff you don't need on your computer." It doesn't have to slow it down, it doesn't have to have an enormous memory footprint when it's running or a huge disk footprint when it isn't, it just has to be stuff you don't need. And depending who you are, that can be quite a lot.
By that definition, the "crapware" winner would have to be most Linux distros. With the exception of machines that are set up for development / production environment, do you honestly think that most people go through each package, one-by-one to determine their need or do they just select the "Desktop" option (for example)?
The last installation I did had somewhere near 1000 packages and I would put money down that I, as a "power user", have used less than 100 of them. They are there, though, in case I ever need them since disk space is cheap and that really is the only cost for them.
