Since it seems #Google has decided to uni-laterally force through their new anti-#adblock #DRM euphemistically named "Web environment integrity", I decided to add a little bit of code to my website that blanks out the page and displays a protest message with a link to the firefox download page when you visit it from a browser with this DRM feature. Here's the source inside one toot, feel free to copy and put it at the end of your website's <body> before the closing tag:
<script>if(navigator.getEnvironmentIntegrity!==undefined)document.querySelector('body').innerHTML='<h1>Your browser contains Google DRM</h1>"Web Environment Integrity" is a Google euphemism for a DRM that is designed to prevent ad-blocking. In support of an open web, this website does not function with this DRM. Please install a browser such as <a href="https://www.mozilla.org/en-US/firefox/new/">Firefox</a> that respects your freedom and supports ad blockers.';</script>
@jaseg Replace Firefox with Librewolf.
