AI didn't kill ClipartOf...
"all you can download for $10 sites" did.
Who would pay $30 for a single vector when they can get unlimited vector downloads for 1/3 of the price?
That too. The free and the all you can take sites, are hurting all around.
But, I'm not a fan of AI, the point is, anyone can go to one of the AI sites and type in some words and have an illustrations of what they need. Many places, accounts were free like Dall-E, until last year, and there are still ways to make free illustrations.
It's just sad to see a quality site, going out of business because the market and the industry has sunk so far. Microstock became Pennystock, has become Nanostock.
