I just saw via a post on Reddit [0] that Netflix IS going to adding ads, or at least offering a lower/cheaper tier that has ads. But we all know where this ends and even if ads don't creep into full-price subscriptions I'm about done. I'm struggling to point to a Netflix show that I couldn't live without, or couldn't binge in less than 1 month if needed. The main reason I still have my account, and why I kept it through the price increase, is I have at least 4 friends mooching off my account. Looking at watch histories they all use it more than I do by a long shot, my last watched show was in January, they all have multiple in the last few days. If they crack down on password sharing this I'm out as well. Really it feels like just a matter of time, sharing crackdowns, another price increase, or ads and I'll cancel.
Well in your situation, it's good for Netflix if you cancel. You have multiple friends using the service via your account (by your own admission) that could potentially convert into paying customers on their own.
