Dear OP, this whole conversation makes me think of the bullying towards open source developers, which can be seen on and off since years.
Let me also share what I have seen on Mastodon : Unlike on Lemmy, Mastodon has had support for ALT text descriptions for uploaded images for some time. Several people have been complaining when people do not add such ALT text, and even bots were made, that you could choose to follow, for people to have themselves reminded that they forgot to add ALT to an image. What I have seen several times is that people were helpful by responding and giving an ALT suggestion to the OP. That would be complaining and helping in one.
Here in this post conversation several people have asked OP for descriptions and then some tension came up. None of the people complaining took some time to add a description themselves and appear to want to make the OP do extra work.And I understand that the OP is not obliged to do that extra work. Regardless of all this I think that a nice solution here would be if OP or someone else creates a new Lemmy community with a name like e.g. selfhosted_software_releases (For open source software releases there is a Lemmy community like that. Can't be bothered to search for the name now) which is only for software releases for self hosting. Then this and other selfhosted Lemmy community can have the announcement of that new selfhosted_software_releases Lemmy community as a pinned post or in the sidebar. The advantages of that :
OP and others will not need to add descriptions
Interested people can quickly see when there's been new releases
Others can have a peek at software names they never heard of before and dive into the details
Selfhosted communities will go back to peace mode ;-)
