It's definitely a topic of conversation in Reddit, etc... However I agree that the push to reduce US dependence by EU companies (and countries) is hampered by the fact that US stuff is already embedded (Microsoft but also Google, etc...) and that many of these companies are transnational anyway (very few European companies are solely inside the EU) and finally and most importantly just about every company will choose the option that does the job best for the right price (sovereignty is a distant second for most decision makers).
