Maybe a service like this should start with ads and paid plans (that unlock restrictions), keep their running costs low, and never stop being an image hosting site?
Too many start without ads, get users and some investment and then spend it all on expensive AWS hosting/CDN bills and employees that are hired to create a social media platform... and then they stop being an image hosting website, fill the site with ads, focus too much on growth, and so on. I don't blame them for taking a big pay check, but I don't think the entrepreneur type works well for image hosting.
