Right to be Forgotten, GDPR, and now this... pretty soon the barrier to entry will be so high that no new players would be able to get off the ground with an internet company in Europe.
a) Regarding the right to be forgotten and GDPR, can't you handle it manually when you're small and automate it when you're big? Complaints should be proportional to the number of users, so it hardly seems like a problem.
b) Article 13 is apparently "a proposal to end the appearance of unlicensed copyrighted works on big user-generated content platforms". I don't know what "big" means, but presumably it excludes "new players" that haven't gotten "off the ground".
Edit: typo... t-shirt
Right to be Forgotten affects search engines. GDPR is common sense, allow users to delete their data. If you make aggregate data of your users and their behavior then it's not their data anymore.
Tax law is a lot more complicated yet never stopped anyone from innovating if there was an economic niche waiting for them.
Of course tax law has stopped people from innovating. It's one of the biggest drains on competition and economic growth. Taxes would be the biggest source of economic efficiency even if they weren't as complex as they are.
However if you don't store raw logs forever it should be okay.
