Yes, there are plugins (e.g. widevine) that do DRM and they have/had varying browser/os compatibility.

But ultimately, Netflix is just trying to check a box in their contractual obligations, and/or prevent high-schoolers with chrome dev tools from sending movies to all their friends. They're not really interested in spending large sums of money to figure out your browsing history. It's just not relevant to their revenue stream.

> Of which Netflix is a part of.

I was referring to businesses that do web activity tracking as their primary business. Facebook and Google's primary business is advertising, which isn't the same thing, and they control enough products that they don't actually have to do very much fingerprinting in order to target ads effectively. Most of their data, people voluntarily hand over. I was getting more at the big ecosystem of commercial tools that others can implement that do these sorts of things. e.g fingerprint.com and many others.
