YouTube: you want 3 months of free YouTube premium? YouTube originals!!!

YouTube: oh, did you ever wish that you could play videos in the background?!

FUCK NO!!! I've got NewPipe and youtube-dl for that!!! The latter even combines nicely with my BlackPlayer EX!!!

Open source is amazing. The ability to just say no to those profiteering gluttons because you already have what they're offering as a "premium feature". Fucking awesome!

Blender.

3D modelling, UVs, texturing, animation, video editing, compositing, motion graphics, motion tracking, 2D animation, and a fucking powerful render engine? Check.
Great community? Check.
Powerful and easy scripting system? Check.
A well organized dev team? Check.
People who care about UI/UX? Check (look at Blender 2.8).
Does it compete with a major corporation that would go into sloth otherwise? Check. (If you thought M$ was shaftware wait till you see Autodesk)

There are other FOSS projects that I really like, but my vote definitely goes to Blender.

Jesus goddamn Christ, fuck all the poorly designed UX. I wish there was an API for everything, it would make everyone's lifes way more pleasant

Thank you community for letting me know about Digital Ocean's Hacktoberfest. Since I have been contributing a lot to open source lately, I got a mail as soon as I registered for Hacktoberfest that I have successfully submitted 4 PRs. Now patiently waiting for my swags. 😀
