People are happy because they can use an app again that they have used for up to 10 years.
What is the threat? Isn't it good that the fediverse is becoming more mainstream? If thread users can communicate with us, it will be easier for them to join us.
My guess is that "all" technically just is a bunch of communities the app developer has chosen to be under all.
I would like to have an app with different themed views. Like a tech view showing all my tech communities. Maybe a meme channel with only meme communities and so on.
With wefwef I got access to All which is all I was missing leaving reddit sync behind
I learned the basics of docker by using synology and unraid. They make it really easy setting up docker apps.
I have had most success installing stuff on my Unraid server. But an old windows laptop will work for sure too. There is a lot of good guides on YouTube and the https://trash-guides.info/ are valuable too!
