It seems the mistake here is that they trust any tech company at all. Is there any reason to believe European tech companies are better?

Germany, France, Belgium, Spain, Italy, and Poland, where Poland has by far the highest rate of trust in US and Chinese tech companies. Seems therefore like the five other countries might not be a representative sample of Europeans, even though total Polish trust of US tech companies still only amounts to 38% compared to ~15% in runner-up Italy.
