It gets worse: In 2024, public EU tech companies paid just €3.2B in income tax. Meanwhile, the EU fined US tech companies €3.8B, which is MORE than the combined tax revenue from all public EU tech companies. And, if just SAP moved from Europe to the US, the EU would lose ~50% of this tax revenue. The EU is basically funding itself through fines on US tech.
You can't make this up: Google now has a literal line item in their quarterly reports called "European Commission fines." $10.5 BILLION as of September 30th. The EU has become so heavily regulated that fines are a "normal" line item now. What is happening in Europe?
Readers added context they thought people might want to know
The €3.2B in income tax cited covers only select software/internet firms, not all public EU tech companies; major firms like Siemens (€2.32B), ASML (€1.68B), and SAP (€1.61B) paid more individually in 2024. assets.new.siemens.com/siemens/assets… ourbrand.asml.com/m/44f4524a27c5… sap.com/integrated-rep…

🚨 There’s a large-scale supply chain attack in progress: the NPM account of a reputable developer has been compromised. The affected packages have already been downloaded over 1 billion times, meaning the entire JavaScript ecosystem may be at risk. The malicious payload works by silently swapping crypto addresses on the fly to steal funds. If you use a hardware wallet, pay attention to every transaction before signing and you're safe. If you don’t use a hardware wallet, refrain from making any on-chain transactions for now. It’s still unclear whether the attacker is also stealing seeds from software wallets directly at this stage. Excellent report here: jdstaerk.substack.com/p/we-j…

This attack targeted Presidential candidates, former Presidents, Cryptocurrency companies and their CEOs through twitter. Social media platforms are a huge vector for attack. CipherTrace is working with customers in government to trace the funds, and find the perpetrators.

Obviously this *should* be a Ph.D thesis in some discipline. But which? AI, with a specialization in time series prediction, is an obvious first choice. What's not obvious...
