HDCP strippers will probably keep working, but committing crimes like circumventing DRM only gets riskier as our computers log and report back connected devices, what we're doing on them, and companies can buy up our purchase histories.
I do admire your optimism, but I've seen our freedom increasingly restricted over the course my own lifetime too. For example, the idea that Microsoft was overstepping their boundaries and taking inappropriate liberties with our computers has been around since Windows 95, but there was a time when I never thought we'd see a day where MS was openly snooping on user's personal files or plastering ads all over their OS yet here we are.
Don't underestimate surveillance capitalism and the desire companies and governments have to restrict what we're able to do with our own devices.
