I think that this is Bacterial Speck/Spot. These are tan in the center and haven't any yellow rings around the spots. Wetness on the leaves is a major contributor to the problem.

I'm not sure about the spots and curls (it could be a number of diseases), but by the color, your plants look like they could use some sulfur or sulfates. Epsom salt is a sulfate. I don't mean the purple from the anthocyanin. I mean the kind of fade the green has.

"Don't eat symptomatic fruit" means the fruit with tiny black splotches all over it. The fruit in your pic looks just fine to eat. You only need to dispose of blemished fruits.

Enjoy that tomato!!!

I've had Septoria on tomatoes. It's not pretty and can decimate a crop! On the up shot, copper will help. It does overwinter in the soil though. Here's a picture of mine:
