This is such transparent EU Bureaucracy shilling. No wonder Europe doesn't have any large SaaS companies with their stabbing unfriendly business climate.
The stabtech industry will just change to Stab-Into-The-Back technology, because every user hates to be stabbed in the chest, but doesn't care if it's not seen.
I think you are factually wrong: Skype, Spotify, Revolut, Zendesk, Transferwise... There are quite many European unicorns too (less though than US and Chinese companies) which are operating as SaaS. Some of them got acquired or re-based to other countries though
