Self-hosted means that it will be served from your own servers, and thereby your own domain. So unless your domain is on a block list, it will be loaded.

EDIT: Sorry, I've been dealing with uBlock Matrix for too long, and forgot how advanced the other blockers pattern matching is. See the many responses to this for better information.

(my apologies for the tone - I have edited the post to try to keep it purely fact based)

From EasyPrivacy[1]

    /piwik-$domain=~piwik.org
    /piwik.$script,domain=~piwik.org
    /piwik.php
    /piwik/js/*$domain=~piwik.org
    /piwik1.

    /piwikTracker.

This doesn't include any renamed versions, nor does it include the numerous domain-specific variations.

Slow down there guy, it was a simple mistake. I've been using uBlock Matrix for too long is all.

The EasyPrivacy block list contains an entry that will block the piwik.js file. Of course, when you're self-hosting, it's trivial to serve that file with a non-default name.

That's an interesting choice. I mean, it's not like you can hide from the web server that you are making the request. But then again, I'm assuming -- by the sheer necessity of having a JS file -- that they are collecting some additional metrics not available to the server in the request.

Those filters could be in place to block the Piwik cloud service: https://piwik.pro/cloud/?pk_source=Piwik.org&pk_medium=Cloud...

It will probably take awhile, but trackers will move to aggregating log files, and blockers will move to TOR. And the arms race continues...

Piwik for example already can import log files: http://piwik.org/log-analytics/ as an alternative to JavaScript tracking

No it parses web server logs, however as mentioned above it doesn't work well for very high traffic sites.

Piwik relies on client-side JavaScript for tracking, not log analysis.

They have both, most users use the client side javascript. I'm not familiar with how well the log analysis works.

Sorry, I was not aware of that feature.
