You’re right to point out the difficulty of preparing installation media.
Also, for the average person, friction will probably happen during installation - possibly having to circumvent safe boot to install and run a new OS (knowing how to enter the bios, feeling comfortable playing around in the bios, knowing how to even disable safe boot once you’re there, not exposing your device to security vulnerabilities by having safe boot disabled), the need for an existing understanding of how partitions work and how the partitions are structured on your specific device in order to test the waters with a dual boot setup on a drive that has data/functionality you want to preserve. Needing to know the ‘what’ and ‘why’ of swap, /home, and /root partitions. These points all came up on a recent installation, and I’m sure they would scare some people off.
Installation will be easy if you have the time, motivation, existing knowledge and/or bandwidth for a learning curve. But not everybody has that.
And that’s just installation, to say nothing of the actual use of the desktop environment, which is not as intuitive as its often claimed to be.
As a user, ‘privacy preserving attribution’ is unappealing for a few reasons.
It seems it would overwhelmingly benefit a type of website that I think is toxic for the internet as a whole - AI generated pages SEO’d to the gills that are designed exclusively as advertisement delivery instruments.
It’s a tool that quantitatively aids in the refinement of clickbait, which I believe is an unethical abuse of human psychology.
Those issues notwithstanding, it’s unrealistic to assume that PPA will make the kind of difference that Mozilla thinks it might. I believe it’s naive to imagine that any advertiser would prefer PPA to the more invasive industry standard methods of tracking. It would be nice if that wasn’t the case, but, I don’t see how PPA would be preferable for advertisers, who want more data, not less.
As a user, having more of my online activity available and distributed doesn’t help or benefit me in any way.
