Apple Music is quite good. Better masters, good recommendations, no fuss - and they pay artists more, supposedly.
Plus actually shitty UX/UI people like to call good, but it lacks plenty of really really basic features. Like having control over if a song is added to the queue to be played next or last, or just being able to preview what stations are going to play (it's a minefield of an UI to try and find new songs while also not interrupt the current one).
And by "doesn't work" it just says "an error occured" and nothing helps. I've even reinstalled it. Judging by reddit posts about it, it's a common issue. (Its logs also provide 0 hints about the error it encounters.)
They don't. Spotify pays out roughly 66% of their revenue as royalties, while Apple Music only does about 50%. [1]

The article you cite actually claims the latter is true, so it seems looking at just that statistic is misleading.
Man, I really, really hate this situation.
