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

Everything else is the alternative.

I have used telegram in the past and while I dont use it due to privacy concerns, it does have some advantages and convenience features to it:

• the integration with bots allows for quite interesting applications such as interactive elements like voting or other automated behaviors
• it's really fast as you never download anything as it's all in the cloud
• because it's all in the cloud you can access your chats from any device, even new, without downloading or backing up your conversations

Here's a list of a few possible reasons

• UI differences
• Features
• Not Microsoft
• Open Core
• Different CI/CD syntax

It's still git under the hood and shouldn't make a difference in most cases.

GitHub is owned by Microsoft

Gitlab is OSS, and you can host yourself

(Ik most don't and use the public instance) Gitlab has features that GitHub don't have, or are better at somethings even if GitHub have them

1. Selfhostable gitlab-runner, faster build and deployment
2. Better permission management for organizations ( per repo, branch, registry etc)
3. Groups, project repos can be in groups

^ Some reason why my organization use gitlab over GitHub, I personally use Gitea.

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.
