It doesn’t appear to rely on ALARM, does it? I haven’t dug through the sources thoroughly yet, but I haven’t see anything there that indicates they’re using ALARM stuff.
Linux definitely has HDR. I’ve been using Bazzite with Steam Big Picture mode as my TV interface for years and can use HDR just fine.
I definitely recommend piracy, but there are also ways to get streaming services to send full quality streams. I won’t recommend them though, because you shouldn’t have to do it in the first place for a service you’re paying for. Just pirate and use a media server or something like Kodi for a nice interface for local files.
First, using Rust does not in any way mean that you’re forced to use pushover licenses. I license all my Rust code as GPL.
Second, I hate pushover licenses, but I don’t see GPL projects using pushover licensed code as a problem. You’re essentially relicensing the pushover licensed crap as copyleft, which is a good thing. Any improvements that they make to MIT licensed stuff will only be available to other copyleft project, thus making the base MIT stuff less appealing.
Did ALARM have reproducible builds? They go into that in the article.
