I believe that the blame here is mostly misattributed.

Caching (a good thing) and also the remote sites being bloated. I'm not sure if or should the browser be fixing that ?

And yet the problem doesn't seem to affect Safari or Firefox. So, people only visit bloated sites in Chrome?

No, but it sounds like Safari and FF are not caching as aggressively. After all, unused ram is wasted ram.
