*is the current implementation of zoom illegal in the EU because it doesn't follow data privacy laws? yes
regularly speed in their cars?
incorrectly dispose their waste?
use illegal narcotics?
not correctly pay taxes on things they sell?
Because most people don't care and risk of getting caught and then being fined for it is low enough.
Someone has to file a complaint at some national watchdog, who then investigates (which can take a long time), and then can fine the business. This happened only a handful of times in the EU over the past few years, not sure about Zoom specifically.
