Blocking unwanted connections with a ’hosts’ file is a very efficient and convenient way to install an undetectable ad blocking system: web sites trying to prevent you from accessing their contents because you are using AdBlock Plus, µblock Origin or a similar utility will not know you are immunized against their toxic material. So, their retaliation policy will fail.
Additionally, those offending sites  will be prevented from messing up your device with third party cookies, web bugs, spyware and hijacking code.
Incidentally, you will use much less bandwidth.
