I really don't understand the negativity here.

If you have a plugin that has 30+ modules, then you only activate 5 of them, then only 5 are doing something. The rest shouldn't have any impact on your site's performance. Although I haven't checked Jetpack's source, I would think that they would have coded it this way.

If you split Jetpack into 30 or so modules, that would just be a hassle. Imagine you'll have to install & activate multiple plugins instead of one. Assuming my earlier statement is correct, the resulting performance would still be the same. Those unused modules would now just become uninstalled plugins. The only difference now is that you're hassled with multiple plugins.

A bigger download versus installing a lot of little plugins sounds better for me. In addition, download size for me really doesn't matter, as long as the performance and loading times are good.
