Printing (even text) is also a risk: It's very likely your printer is secretly adding marks to the page that contain its serial number and the current timestamp. [0]
Meanwhile Microsoft (and Apple) have "telemetry" harvesting those serial numbers of all internal and external devices you've ever had connected or reachable. Then they link them to your MS/Apple account, IP addresses, and the extended social-graph of all computers that were ever in the same room or shared the same bluetooth speaker.
In short, your "anonymous" flyer critiquing The Regime and depicting Dear Leader as a clown could lead thugs straight to your door. Or to the door of whomever you're staying with.

It's most likely how the FBI caught NSA leaker Reality Winner:
> Both journalists and security experts have suggested that The Intercept's handling of the documents, which included publishing the documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker.

and then in few years a new mono-mustachioed or mono-browed leader will emerge who declares memes a blasphemy punishable by death and will call up all the telemetry gathered to punish all involved.
You know a certain dictator denies access to the country they control based on whether visitors "like" them? They use a private militia, funded by stealing from taxpayers, in contravention to that country's laws, to target citizens who are not supporters of them. Some of those citizens get shipped abroad to foreign prisons by these militia. Others get shot in summary executions in the streets - the controlling regime covers it up with false media reports, and uses corrupt judges to evade scrutiny ... a certain software company support that regime, even acting against foreign scrutiny on their behalf.
Essentially all of that country's businesses that are close to the regime need to be considered hostile.
We don't need to wait a few years, the revolution already happened; the insurrectionists were freed. These companies paid their tributes, in dollars, to the regime.
Maybe next ML will be integrated into software suites to enforce that regime's lies? Most Western governments use such software, the distributers of which have already shown they'll act in the regimes interests against supposed allies...
