I'd like to point out that Qonto is a business bank. Not open to consumers. They also have a list of prohibited activities: (https://legal.qonto.com/en#template-uoa8xux5p) which, funnily enough, include "Hunting, trapping and related service activities", "mining nonrenewable natural re-sources" and "accessibility diagnosis" (??).

Consumer protection laws obviously don't apply to businesses, and banks close business accounts all the time for not following the terms of services. That sounds like a MUCH more probably cause than "I said mean things about Palantir".
