I happen to be a small business owner in the EU and I have many customers who are the same. We all have registered with the ICO (UK) for something like £60 pa and filled in a short questionnaire. We have read the clear guidance on what records to keep and what to not keep - it's not rocket science. That is GDPR for most small businesses. Now, if your business is predicated on building profiles on people or pestering them on the phone or flogging ads etc then I can't help you there - it may be a pain.
Now Article 13: It is designed to try and make the likes of YouTube responsible for not carrying copyrighted works by putting the onus back on them. I believe they hide behind carrier status. I understand that A13 looks a bit like an anti-meme effort but it isn't because that is generally covered by parody or reasonable use regulations.
In the end, are you really sure you want the world to block us?
