Prime Video + Prime Shipping + Prime Music is ~16 USD per year if you get the subscription from India.
I used to live in India but not anymore. So I was keen to only use Prime Video + Prime Music (since Prime Shipping doesn't work outside of India for that sub).
Both Prime Video and Music were rather unsatisfactory, and no Chromcast support was just the last straw for me to unsub.
This is probably why use one-time-password via SMS is so rampant in many many services. This kind of auth has mostly eliminated large scale hacks, however OTP over SMS still won't help targeted hacking. But in general the public at large are rather safe primarily because of this.
Having said that, subscription based startups struggle due to the the compulsory use of OTP and therefore resort to yearly subscriptions rather than monthly (ex: Amazon Prime).
Clearly this is well orchestrated and professional. I'm wondering what could be the motivation for such an attack. There is no monetary benefit whatsoever. Perhaps some AI company wanting to acquire solid data to train their models?
