> Isn't the EU making more money from fining US tech companies than their own tech companies are paying in taxes at this point?

No, this is a common piece of Trump era propaganda. The EU does not levy such a general corporate tax, fines are not recurring as taxes are, fines like this one are done by a single member state (Italy in this case) and do nothing for the EU's budget, and the big tech companies within the EU are private companies whereas this misleading stat picks the rare public ones for its comparison
