Changes to the #Chrome extensions API mean that ad-blocking will effectively be limited to enterprise (read: paying) customers. #Google even admits that ad-blocking is a thread to their revenue stream in recent SEC filings.
Google is essentially saying that Chrome will still have the capability to block unwanted content, but this will be restricted to only paid, enterprise users of Chrome. This is likely to allow enterprise customers to develop in-house Chrome extensions, not for ad blocking usage.
Google themselves have even admitted as such in a recent SEC Form 10-K filing by Alphabet, uncovered by Hill, in which ad blocking extensions are labeled as a “risk factor” to Google’s revenues. — 9to5google
As Google themselves put it:
New and existing technologies could affect our ability to customize ads and/or could block ads online, which would harm our business. — Google's SEC 10-K filing
Not only will this affect ad-blocking, but other extensions that use content-blocking as well - for example, certain accessibility and content-warning plugins could equally be affected by this change.
Google Chrome is moving to remove autonomy from Web users.
Google Chrome is not built for people; it’s built for Google, by Google. You are their bank. — Jacky Alciné
