The cat is out of the bag. Everything what those services do is like child’s play compared to the stuff you can do at home on your own PC. This ain’t ever going to stop, it’s just going to get more powerful.
I recommend playing around with Bing Image Creator/DALLE-3 for a bit to get an idea of what is possible these days. It will filter celebrities and NSFW content of course, but the amount of flexibility it has and quality it produces is mind boggling.
