You're being lazy. This law has been under work for years, was going against massive corporate interests and was heavily lobbied against.
It's a minor miracle we have it at all.
The enemies of privacy, advertising drones, the brainwashed and careless love to attack it because it's hitting their pockets or making them click away some inconvenient pop-up.
I know of a few companies that decided to stop selling customer data to data brokers due to GDPR. Now its impossible to know if you were specifically affected by exactly these companies' business practices. But if you're in the EU you would have to live a rather strange life not to be affected in some way.
One of these companies was an airline. They would share the price you paid (meal you chose, etc.) with among others, a company specializing in "individualized pricing". Meaning: if you flew business class, the telecom company might just not show you the cheaper options next time your contract is up for renewal.
