i mean, i can't think of a proprietary application that does everything that blender does, so there's no need to list blender as an 'alternative' i guess.
i'm not particularly familiar with the 3d modeling space, i've only done basic stuff. feel free to correct me
I work in Architecture and fully transitioned our firm from using 3dsMax and Vray with Blender just before the pandemic started. Haven't looked back ever since. Blender does a lot of things but for the most part, it's an alternative to any mesh based 3d modeling and sculpting program. E.g. 3dsMax, Maya, C4D, Zbrush, etc.
Hey , so you need to add REAPER to the audio editing list here, even if you feel a need to put an asterisk next to it. Development is extremely open and advanced. Really the only reason it's not foss is because it was built on using elastique which is proprietary. The developer lead dev (Justin Frankel) is a very outspoken advocate for foss and has a plethora of open source software available. And to add to this REAPER is the most advanced, efficient, and full featured option in the entire world of audio software so it should be a real point of pride for the community and I'm sure if you asked any of the devs who develop the other audio programs on the list, they would say the exact same thing.
You can get NewPipe from F-Droid if you're on Android. It does PeerTube and even Bandcamp streaming. It also allows you to use YouTube ad-free - and there's a version with built-in SponsorBlock for skipping those in-video ads/promos.
For Android have a look at NewPipe. You can add PeerTube instances and watch there.
But AFAIK it was removed from the Play Store because it lets you watch YouTube Videos without Ads.
