Seeing as Plausible is still a script, how much of the remaining percentage of Firefox/Linux users are blocking scripts entirely? My default uMatrix settings block everything but first party CSS and images.
Considering that most of the web is unusable for most people without javascript, I'm pretty sure no-script people are a very very small portion of the internet.
A lot works quite okay, reader view also works great a lot of the time. And if necessary I'll allow first party scripts and most tracking scripts are third-party.
