Hosts files are literally the devil. They break so much shit. Hostnames sometimes change behavior (like an ad server that starts hosting a redirect script for legitimate clicks), kids who are "good with computers" set them up on relatives computers over the holidays unmaintained, malware that uses them to block antivirus updates, etc.
If you want to block ads, fine. Use a content aware proxy or browser extension.
