That's only the DSA, it's only a small part of web regulation in the EU.
Overall there is very little in the way of exceptions for small businesses. Similarly with the EPR / PPWR changes that went into effect on the 12th of August, a lot of owner-operated microbusinesses have had to stop shipping to many EU countries due to the crazy costs of registration (which has to be done in each individual EU country no less, totally contrary to the idea of the EU): https://ppwrconnect.com/blog/ppwr-applies-12-august-2026-who...
Some artists send only one padded envelope to some countries (or none, in some years) and have to deal with hundreds of euros of registration cost for some countries. It's ridiculous. There's 2 little pieces of relief for microbusiness but most of the crazy red tape applies.
The problem with their regulation is that the big ones that were meant to be targeted (e.g. Google and Meta) have plenty of lawyers to sidestep all the regulation, and the small initiatives are all killed because they don't have such capabilities. We're still tracked by Google and Meta everywhere.
And then there was the 3 euro per product type surcharge on small packets, making it impossible for small artists to buy items that cost 20-30 cents a piece. Legislation lobbied for by the big buck chains like Lidl and Ahold.
To be honest I'm now strongly in favour of reeling in the EU project to simply some economic treaties and easy movement of people because they've become a stringpuppet for big business lobby. Definitely not some big federal state (we've seen where that path leads in America)
