We feel the performance benefits are worth it, and it is trivially disable-able in site settings.
If you have any suggestions for more severe and extreme “we do not care about tracking anyone, this is only about performance so everyone that uses Discourse can have a good experience” policies or files or notices we can put in place, beyond what we currently have, let us know – happy to do so.
We do not have any form of logging enabled for this service, for both privacy and performance reasons. Happy to go on record with that, in as many ways and places as needed, happy to have a third party auditor of your choice come in and verify that as needed.
