I've told my story about how I pushed Daniel to post the source code for loops by pixelfed, of course a lot of people don't like my methods which i understand. My morality and logic is just different.
It correlate with me posting my story on Lenny for the past few days. I won't looking into the code posted. Someone else can verify if the loops code matches the APK you get when making an account from the website.
After 5 years of development loops is becoming open source and passionate people of the fediverse can hopefully improve loops.
As for me I'm hoping to build up niche communities in the fediverse so there more engagement.
Lemmy seems to be a very powerful part of the activity hub protocol
The backend is the more important thing since an app without backend is worthless. The Backend is also the part that can form the infrastructure, saving and accessing of media, subscribing to others and ultimately federation in the fediverse.
