> It's completely missed that small entrepreneurs may also want to take part

There's truth to this but it's an overstatement as it stands. For example, GDPR rules are less strict for small companies.

Please elaborate on less strict rules for Gdpr? There is Record of Processing Activities exemption for <250, but if you have to comply with Gdpr (and you do), you need essentially same info as Ropa and of course it has to be up to date. How else can you ensure you are in compliance?
