If the data hasn't changed during the last interval, then it doesn't rewrite the file. The article mentions loading a couple of dozen pages that are probably all pinging a dozen ad servers every 15 seconds, updating their cookies and localstorage with the results, etc. It all adds up. If you really want to solve the problem, use an ad blocker, or push the pages you visit to remove the bloat.
