This does seem like a weird shift on Apples part. They even featured the app in “app stories” at one point in time.
I’m a user of this app and found it when I couldn’t find caffeine which I used on an older MacBook.
As an aside I’ve noticed that it’s Apples day to feature on the hn front page. Seems to be an unusual influx of bad apple press. I’m curious if it is coordinated? I’ve wondered the same about anti google/Facebook/Amazon as well. They all seem to come in waves.
