No I don't think so. You have to able to take your own data out for free. But delivering it to everybody else can be charged.
Edit: Not allowed to comment on your reply anymore. I read it as a confirmation of what I said. Charging for egress in general is allowed. Only the egress to take your own data elsewhere must be free.
Chapter VI: Switching between data processing services
The Data Act will also entirely remove switching charges, including charges for data egress (i.e. charges for data transit), from 12 January 2027. This means that providers won’t be able to charge their customers for the operations that are necessary to facilitate switching or for data egress. However, as a transitional measure during the first 3 years after the Data Act’s entry into force (from 11 January 2024 to 12 January 2027), providers may still charge their customers for the costs incurred in relation to switching and data egress.
Is that for all egress or just for switching providers? "Move all my data from GCP to AWS, no cost" is quite a different thing from "Host video files for free"
> In order to foster competition, the gradual withdrawal of the charges associated with switching between different providers of data processing services should specifically include data egress charges imposed by a provider of data processing services on a customer. Standard service fees for the provision of the data processing services themselves are not switching charges. Those standard service fees are not subject to withdrawal and remain applicable until the contract for the provision of the relevant services ceases to apply. This Regulation allows the customer to request the provision of additional services that go beyond the provider’s switching obligations under this Regulation. Those additional services, can be performed and charged for by the provider when they are performed at the customer’s request and the customer agrees to the price of those services in advance.
