I’m using nextcloud and I like it (also I don’t see all this slowness even if I run it on a core i3 8100) but it’s the general stance from the devs
Everything it’s announced like it’s ready to the public when it’s just a proof of concept (not even alpha)
Another example is the mail plugin. It’s an unusable early alpha yet on the blog there are three posts starting from four years ago talking about inexistent features nextcloud.com/?s=Mail&wpessid=1612
Same for the forms plugin. Early alpha that doesn’t have an essential feature like emailing responses to specific addresses (it sends notifications via nextcloud). Again the blog talks 4 years ago like it’s ready for everyone.
Or the Trello clone. Many problems like it “ruins” the tasks sync by creating read-only tasks that get synced via caldav.
Or nextcloud photos, big post in 2022 but it’s very barebone
Or docs, so many posts yet it has so many problems.
Or the desktop client, where builds are pushed to regular users without testing the installer script (forced reboots without confirmation, crashing explorer.exe instead of asking a graceful restart)
The only NC plugin that I’m using without problems and that I feel it passed the beta stage is Music and its subsonic compatible server. No blog posts about it. Maybe because it’s hosted on owncloud GitHub repository
