Hi @crazefury, welcome to the community!
This change was done for a more streamlined user experience for the free tier.
For any changes to it you can refer to this FAQ about Spotify free on mobile.
You can actually have a look at all the features Spotify premium has to offer to you right here.
Let me know if you have any other questions :)
