That’s absolutely still true. I just disabled Spotify app link handling, and then Spotify opens in Firefox on my phone. And on Desktop it works the same way.

At least for me in the Netherlands, for the past month if I click a link to a specific song, I get redirected to a page to start a radio based on the artist and encouraged to upgrade to Premium.
I've had to get friends to share the titles manually, before I found Odesli to be able to convert them.
Right, but before it just loaded the page of the album/playlist and told you to sign in to your account. It has never allowed you to play songs without a sign in.
