Is Stylus (beta) safe?
Stylus (beta) applies user-authored CSS styles to websites and includes hardcoded OAuth client secrets for optional cloud sync providers.
Stylus (beta) is an open-source browser extension that injects custom CSS into web pages at the user's direction, allowing visual customization of any site. It supports optional style synchronization via Google Drive, OneDrive, Dropbox, or UserStylesWorld using bundled OAuth credentials. The OAuth client secrets for these providers are embedded directly in the extension bundle rather than fetched at runtime.

Shared hosts - 11 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
