Repeatedly The current administration has stated
* That they would acquire Greenland by any means necessary https://www.washingtonexaminer.com/policy/defense/3361358/us...
* That they would Make Canada part of the US as its 51st State https://www.bbc.com/news/articles/cvg198xxy1xo
* That they would engage in trade war with Europe over alleged imbalance and loss in trade https://www.cnbc.com/2025/03/27/trump-threatens-far-larger-t...
Given this context, if you are not directly in the US or directly a US company, it makes a lot of sense to start to question your future ability as well as future costs for access to US controlled systems.
The President of the United states, its commander in chief, explicitly did not rule out military action when discussing his desire to bring Greenland and the Panama canal under direct American control. The rhetoric of making Canada the "51st state" while less explicit a threat is still one. Greenlanders, Panamanians and Canadians all clearly see these as threats.
And people seem to be learning to take Trump's insane talk seriously. So no, I don't think the connection with LibreOffice downloads is a "load of tosh", but just one example of a larger shift.
And by threatening to invade Greenland (which is Danish territory). And by starting a trade war against EU. And by having the leaked messages of US vice president describing how much he despises Europe.
The US has a very odd way of strengthening an alliance by alienating its allies.
