Other browsers support DRM too, but with different tradeoffs. Chrome uses Widevine, but one of Chrome's philosophies is that you should be able to wipe a Chrome install, reinstall Chrome, and have no trace that before/after are the same person. That means no leveraging machine-specific hardware details that would persist across installs. "Software-only DRM", essentially. Edge on Windows (and Safari on OSX) are able to leverage more hardware-specific functionality --- which from a DRM perspective are considered "more secure", but the tradeoff is a reduction of end-user anonymity (i.e. if private keys baked into a hardware TPM are involved). Last I checked, Chrome/Firefox were capped at 720p content, Safari/Edge at 1080p, though it looks like Edge is now able to stream 4k. |
