If you're not collecting personally identifiable information, you are not affected by GDPR and can proceed as normal. Not exactly sure what "recording facts about the world" means, but if it doesn't involve individuals and their data, you don't have to change anything.

I agree that general information should be free, but there is a difference between general information and personal information. Personal information (like the photos I take in my bedroom) should not be free unless I agree to that.

Once you have shared a picture of your bedroom to the world I believe it should be free to exist. If someone noted that you had a booshelf in your room I don't believe you should be able to have that information taken down just because it is information related to you.

Edit: If knowledge of the bookshelf does not count as personal information instead someone could post your address my crossreferencing the photos with houses that have been sold in that area in the past.
