A list of all decentralised/federated replacements for your day-to-day apps (such as YouTube, Instagram et. al.) as of today (list will grow in time):
🔹social networking platform: https://scuttlebutt.nz/
🔹decentralized social network: https://friendi.ca
🔹federated photo sharing: https://pixelfed.org
🔹decentralised file sharing: https://siasky.net — watch out for this one, you need to encrypt your files before you upload them, they don’t encrypt them 😉
🔹federated video sharing (YouTube alternative): https://joinpeertube.org/
🔹Twitter alternative (decentralized): https://joinmastodon.org/
🔹enjoy & share music (decentralized): https://funkwhale.audio
🔹federated blogging: https://joinplu.me

The difference between these and their counterparts is that they're not hungry for your data (they're not even collecting it), there are no ads and many more features that you can check on their feature site.
