I would claim the opposite. If you're starting a business you'll research how to click your backend together in a way that doesn't leak all of your user's data in all directions. Than you'll build a backend that never had these problems to begin with.

It's much more of a pain for companies that already have a tried and true stack but didn't use the two full years of warning to replace the parts of the backend that isn't compliant. No rest for the wicked.

Ohm that's if you're starting a business, which will now carry a much higher cost.

And if you have a business running, bad news, costs will increase significantly.

As someone trying to start a business : boo frickin hoo. This is not kindergarden, this is adults trying to run a business. The deal of private property and capitalism is: private person figures out how to do things within the law, profitable, and then gets to keep said profits, minus the subscription fee for the society that enabled that business ( taxes). If the law is nonsensical, private person can try to change it. This law is not that. It is what everyone wants for their data, if they can get it. So i'll gladly deal with the headaches, because at least my data is protected by the same law
