I can totally understand people not liking a new password sharing restriction that used to be commonplace. It is essentially a perk being take away. But Netflix is likely just the first for what will be adopted by most in some shape or form.
It may seem like Streaming is very profitable based on Wall Street loud mouthed TV investors and the previously absurd stock price multiples, but it actually isn’t. Netflix is an outlier of profitability but even they didn’t break double digit profit margins until the pandemic. They hit above 15% but it has been falling back a point or two. And this is a 220+ million subscriber base paying nit insignificant prices
There was a story back a bit that Amazon Prime Video loses money as a standalone (sales outside of video makes Prime profitable). Disney+ isn’t profitable but is projected to be so in a couple of years. AppleTV+ is likely a country mile from profitability. If Google TV is actually profitable, it is a bag of coins comparatively and is because of their incredible data gathering and monetization of that data. And these are all deep deep pocketed streamers. Except for Disney, the rest can operate at a loss if it creates profit elsewhere.
Consolidation, price increases, increased ad/data gathering along with password sharing limitations, these are all coming. Once subscriptions peak and level off (and profit is single digit margin) they will begin these ways to cut cost.
