I don't really understand this seeing as you're commenting this on a post from your own instance. Therefore, in an ironic sort of way, it seems like people within your own instance are against the fleeting whims of mainstream platforms as well. So, I agree with your counterpart: you are not owed a lower barrier of entry if the entire idea of companies not manipulating your algorithms and selling your data is for it to be community-driven effort. And so, it is not a lot to ask people to learn how things work so they may be able to service themselves, or even past that knowlegde forward.
No matter how you slice it, decentralized networks require a lot of work and maybe, the people who put their computers and hardware out there to make it possible just want people in that circle to appreciate the work put into it. Not hop on their instance because it's quote, "easy".
Like, the idea of the internet having been more fun years prior was because it was experimental and community-driven. You will need to sacrifice simplicity and functionality for that. And if you don't care about that, well, use Reddit, Discord, or any other service that's easier than this.
Sigh. And this is exactly why I said people need to learn how these protocols work.
