As a commenter on that post says, this sort of talk is also common in the comments of Phoronix articles. The commenter says they’ve completely stopped supporting Phoronix since it’s clear that Michael enables this behavior by not moderating it (the least he could do is disable commenting; the type of people that are in the Phoronix comments are the absolute worst). It’s been festering for a very long time, unfortunately. Click any Phoronix article that’s older than a day and check the negativity. Worse, click an article about a controversial topic like X11/Wayland/Systemd/bcachefs/KDE/GNOME/etc. and it’s just a shitshow.
I’ve been seeing it to a lesser degree here as well. I don’t know what it is about X11 that really riles up the conspiracy theorists.
I’m used to LanguageTool, and at a glance it seems like Harper covers way fewer rules than LanguageTool does. Not sure if this is actually noticeable in practice, but I run my own LanguageTool server and am not too picky about the performance, so I’m not in a rush to move until someone figures out a good way to compare them. LanguageTool’s rules are all open source at least, so it’s only a matter of time before Harper gets anything it might be missing.
