The much maligned “Trusted Computing” idea requires that the party you are supposed to trust deserves to be trusted, and Google is DEFINITELY NOT worthy of being trusted, this is a naked power grab to destroy the open web for Google’s ad profits no matter the consequences, this would put heavy surveillance in Google’s hands, this would eliminate ad-blocking, this would break any and all accessibility features, this would obliterate any competing platform, this is very much opposed to what the web is.
Yep, Safari is still WebKit.
Safari thankfully hasn’t switched to Blink (the engine powering Chrome and all Chromium-based browsers), which forked from WebKit over a decade ago (April 2013).
Safari is only available on iOS, iPadOS, and macOS. In fact, every browser on iOS/iPadOS is WebKit-based, as it’s the only browser engine Apple permits on their phones and tablets. (Yes, this includes the so-called “Firefox”, “Chrome”, and all the other browser apps on iOS/iPadOS.)
GNOME Web (aka: Epiphany) is also WebKit-based and is available on Linux.
There’s no current Windows WebKit browser that I’m aware of. (Apple shipped Safari for Windows a long, long time ago, but also discontinued it shortly after.)
There are embedded ports of WebKit for various devices in the form of WPE Webkit. (WPE stands for Web Platform for Embedded.)
