I run Linux with Secure Boot and I don't feel locked out of any media, applications, or websites.
My mom uses Secure Boot with Windows and doesn't know or care that it's enabled at all.

What's happening the article is what has already happened on mobile: it requires vendor signing to run anything on mobile OS and the vendor locks out 3rd party drivers from their OS entirely.
It's yet another step towards desktop computing converging with mobile when it comes to software/firmware/boot/etc integrity attestation, app distribution and signing, and the ability to use your own bootloader and system drivers. When Secure Boot was first rolled out on laptops, it was used by Microsoft to lock the user out of the boot process before it was adapted to let users register their own keys, it can always be used for its original purpose, and how it's currently used on mobile, again.
