I think this is correct. I refuse to touch Chromium with a ten-foot pole, but there aren't really any other options on Linux. (Yes, there is LibreWolf and other forks, but I doubt any have the resources to "go it alone" should Mozilla fold or go completely turncoat.)

The closest extant option is something like GNOME Web (also based on WebKit like Orion) but the lack of extension support and poor performance makes it a non-starter.

As someone who already pays for Kagi search, Orion will definitely be on my radar. I'll gladly volunteer $5/mo if I can just copy-paste my extensions unchanged and keep browsing.
