I mean, if they show you a notification that you should really sign-up for a paid subscription or disable your adblocker, this does not really seem a big deal for me and all right for Spotify. However, if they terminate your account because you happened to use Spotify for a while on a system with adblocking enabled (does being on a Pi-Hole network count?), I am wondering if they won't just drive a lot of potential customers to Apple Music & Co, which is the last thing they need right now... I mean, if they would terminate my account like this, I definitely would not come crouching back to them asking for mercy to be allowed to sign-up for a paid subscription. I mean, I do have some dignity left.
(I usually use Spotify using their apps, so without ad-blocking, but I cannot guarantee that I haven't been using their web player from time to time, too, and of course my browser has an enabled ad-blocker. I don't pay for Spotify because I buy my MP3s and use Spotify primarily to discover new songs.)
