I seem to agree with most other users in this thread.

Sure, the privacy aspect is nice; most people already share too much information with third parties unwillingly, but I think a good user experience should be prioritised. If option 3 is more likely to provide that, I would choose going that way.

Most people, especially those migrating from other sites, probably care more about the images loading than the privacy involved with proxying them.

It would maybe be nice to have an option to not load external resources automatically, or a black/whitelist for certain sites, if such an option doesn’t already exist.
