Galaxus is an online store that's mainly popular in Switzerland and they only recently started to expand into the EU market. The Swiss can be surprisingly Eurosceptic, so it makes sense that they wouldn't be too interested in any Buy European/Buy from EU movement.
Although they sell other stuff as well, Galaxus is mainly focused on consumer tech products. The fact is, it has not even been a full year since Trump was elected and nobody is going to suddenly come up with products that rival the likes of iPhone on such notice. Consumers cannot be expected to buy European when there's no viable European alternative.
It's amazing how fast it is, even for uncached queries. For cached ones, it retrieves results before I can even mentally register that I pressed Enter.
I wouldn't be discouraged by this article.
