I had the same confusion. I eventually found a quote here (published today, not available at time of up-thread comments):

https://kvia.com/health/2020/03/17/france-says-ibuprofen-may...

> NSAIDs might affect how Covid-19 binds to human cells, according to Dr. Yogen Kanthi, assistant professor of cardiology at the University of Michigan, who studies inflammation. > > "There is data from basic science studies that have shown that Covid-19 itself binds to a protein at the surface of cells called ACE2,” he said. “There is a hypothetical risk that giving NSAIDs like ibuprofen could increase levels of ACE2 shown in animal models, but not in patients."

That's the best I can find searching for '"ibuprofen" "ace2"' or 'NSAID' or 'COX2' in place of 'ibuprofen', so maybe take it with a pinch of salt, and it's not even saying 'yes definite link'.
