My only point is that you don't have a "right" to use the service. The ToS not being legally enforceable does not change that fact. Spotify can kick you off for violating their terms, but they can also kick you off for whatever they want.

Being barred from the service is not some sort of injustice or violation of your rights, especially after breaking the terms.

The people in this thread claiming they can do whatever they want and block ads is true. That does not give them some sort of moral high ground, just because they can.
