Brave takes brave stand against Google's plan to turn websites into ad-blocker-thwarting Web Bundles:
A proposed Google web specification threatens to turn websites into inscrutable digital blobs that resist content blocking and code scrutiny, according to Peter Snyder, senior privacy researcher at Brave Software.
On Tuesday, Snyder published a memo warning that Web Bundles threaten user agency and web code observability. He raised this issue back in February, noting that Web Bundles would prevent ad blockers from blocking unwanted subresources. He said at the time he was trying to work with the spec's authors to address concerns but evidently not much progress has been made.
His company makes the Brave web browser, which is based on Google's open-source Chromium project though implements privacy protections, by addition or omission, not available in Google's commercial incarnation of Chromium, known as Chrome.
[...] The Web Bundles API is a Google-backed web specification for bundling the multitude of files that make up a website into a single .wbn file, which can then be shared or delivered from a content delivery network node rather than a more distant server. It's one of several related specifications for packaging websites.
The problem, as Snyder sees it, is that Web Bundles takes away the very essence of the web, the URL.
"At root, what makes the web different, more open, more user-centric than other application systems, is the URL," he wrote. "Because URLs (generally) point to one thing, researchers and activists can measure, analyze and reason about those URLs in advance; other users can then use this information to make decisions about whether, and in what way, they'd like to load the thing the URL points to."
An individual concerned about security or privacy, for example, can examine a JavaScript file associated with a particular URL and take action if it looks abusive. That becomes difficult when the file isn't easily teased out of a larger whole. Web Bundles set up private namespaces for URLs, so privacy tools that rely on URLs don't work.
"The concern is that by making URLs not meaningful, like just these arbitrary indexes into a package, the websites will become things like .SWF files or PDF files, just a big blob that you can't reason about independently, and it'll become an all or nothing deal," Snyder explained in a phone interview with The Register.
Separately, Google has been working to hide full URLs in the Chrome omnibox.
