I think in general, regardless of whether the European administrations move to OpenSource or not, of first becoming independent of the American companies, which almost without exception create their incomes with surveillance advertising techniques (also FOSS) and focus more on European developments and services, that there are also very capable, for example KDE (German), whose Calligra Suite is also a worthy FOSS alternative. It is always better of using local products and only to use of third countries, when there are no valid alternatives and that the CE has become too dependent on the USA, losing big part of his sovereignty, apart from having to submit to the American conditions that in general respect much less the rights of the user.
