If you’re going to speculate about ulterior motives, fill in the supporting details so people can tell you’re not just promulgating conspiracy theories.
So you think that Netflix has gone to Microsoft to start a multi-year industry-wide standardization process to change how people login because that’s easier than looking at their own log files?
Netflix didn’t crack down on shared passwords when they were growing rapidly but that’s not because they couldn’t.
I don't, but yes; many seriously actually believe this is why the industry is moving to passkeys. It isn't logical, it isn't reasonable, but these are your customers.
Yes, if you're both using the same password manager. But, while you live in Silicon Valley bubbleland, most people don't. The world's most popular password manager is Excel; and sadly it does not support sharing passkeys (or, really, passkeys at all).
Baseless? Can you think of a reason why Netflix wouldn't support it for precisely this reason? Their campaign against account sharing is widely publicized. Do you think account sharing is easier or harder under passkeys? Just because it's a conspiracy theory doesn't mean it's false.
It’s baseless because it’s pure speculation without any evidence, or even a coherent argument for why they’d go to so much work for something they already do at much lower cost.
That only works if the share target is using the same password manager.
If you asked most people "what password manager do you use" they would give you a blank stare; but sadly, the answer is rarely "I'm not using one" the answer is usually Apple or Chrome or whatever is built in and most convenient.
