If you're a large enough entity operating in multiple jurisdictions around the world, you're exposed to such a byzantine labyrinth of laws and regulations that it's impossible not to be in violation of some rule or law, somewhere, at all times.
Regulators know this. They use discretion to decide when and how to enforce these rules. Some are seldom enforced, others enforced with reckless abandon depending on the administrator, market conditions, political winds, etc.
Every regulated financial institution, for example, and I mean every single one, will be fined for something if it is big enough and has been around long enough.
Basing fines on worldwide revenue is a ridiculous way to ensure absolutely no risk-taking happens, because innovation happens at the margin. Tomorrow's massive industry is today's grey area.
There's a difference between risk taking in doing something new and innovation and risk taking of riding the line of legal/illegal. I for one, would much prefer an environment where businesses were a little more afraid of breaking the law to exploit people/environments/other businesses/etc.
It’s a response to the “insanely dangerous” actions of the industry.
"Forcing" companies to pull out in this manner would instantly ignite a trade war between the US and the EU.
This is a no-win situation for the EU - if WhatsApp is shut down in the EU, for instance, it will cause massive problems, loss of life and money, etc. Whatever new solution arrives on the scene will struggle to turn a profit and probably be even less compliant with regulations for many years due to the sheer amount of regulation that has slowly accumulated.
Please explain how WhatsApp shutting down in the EU would cause "massive problems, loss of life and money" rather than e.g. Signal having two weeks of instability due to 200M new users and that being the end of it?
Emergency services in some locations rely on WhatsApp, most businesses use WhatsApp to communicate with customers. You'd have to re-build your whole network on another app. Signal may be that app or the ecosystem might simply fracture.
If the fines are small, people complain that they have no teeth and that corporations just see them as a cost of doing business.
If the fines do actually have teeth, we have your comment here.
What would you consider acceptable?
The real solution is not over-regulating the internet. This is how we end up with the comparatively barren tech landscape of the EU, or the trend towards authoritarianism in Brazil, where a massive platform was banned simply because some small and questionable rulings were ignored.
The innovation aspect really bothers me. As a SWE you definitely feel the development burden of so much regulation, it is huge, and that's with the might of a large company and all that brings to support you. I can't imagine startups will ever even attempt to meet these regulations.
My own experience dealing with regulation in big tech makes me believe this is one of the chief reasons the EU has experienced technological stagnation. Maybe good in the short term, very bad for humanity in the long term.
Most of DMA targets only "gatekeepers" (i.e. big tech), not small startups.
