I tend to agree with you in that most people are too addicted to the convenience. But yeah, Balaquina does make a good point. After all, a commonly cited reason as for why the Fediverse won’t rival mainstream sites is that making an account is more complex. Even then, it’s just choosing an instance, which isn’t that hard, it’s just more complicated in comparison to, say, Reddit or Twitter. So following the same logic, it very well could backfire if Spotify raises the barrier of entry (or barrier of continuous entry, for those who already have accounts that they will have to verify).
