This thread is worth reading if you are a Google docs user.

Short version: When you export a document from Google Docs, Google replaces all your hyperlinks with links that allows Google to monitor the interactions of everyone you share your document with.

This hidden link replacement can potentially be used to build a model of your professional relations, where people who interact more with your content are considered a stronger relation.

Think about the implications.

@randahl this is good to know!
If I share in future, I'll export a PDF that I will edit to roll-back links

I know I say this a lot, but I am glad I stuck with WordPerfect. Usual evil stuff from #Google.

@randahl

Wow, so Google has to keep a database of all these links online indefinitely ... that's robust. For the sarcasm-impaired: that was sarcasm.

And, they can decide which document's links to "break" when they feel like it.

Stop. Using. Google. At. All. For. Anythhing.

@randahl I am planning to replace at least Google Photos with a self hosted FOSS solution, but last week I lost an entire day replacing a HDD that was almost dead (after years of torrenting). I prefer self hosted, I don't want to switch to other hosting, even if they have E2EE, but maintaining things can be annoying sometimes.

@randahl there’s nothing they won’t do to steal ur data. I suspect Microsoft is doing something similar, if not they will now.

@randahl Graph theory and email spectroscopy, an HP research paper from decades ago later used by IBM in its NORA (non-obvious relationship awareness) application.

@randahl

According @Joe_0237 documents are only affected when exported to html or epub:

txt - unaffected
html + AFFECTED
odt - unaffected
pdf - unaffected
epub + AFFECTED
rtf - unaffected
docx - unaffected

@stekopf you are right. Thank you. I updated the post to reflect that this is export related.

@randahl I need to test this on our Business Workspace to see if it is limited to public use or widespread

@steve do note that it is related to export formats — e.g. HTML is infected.

@randahl yes, noted. Not sure how often we need to export to HTML but I’m curious now

@randahl Time to add a few links to potentially hazardous stuff just to poison the algorithm
