I expect all hosted model providers will serve ads (regular, marked advertisements, no need for them to pretend not to, people don't care) once the first provider takes the lid off on the whole thing and it proves to be making money. There's no point in differentiating as the one hosted model with no ads because it only attracts a few people, the same way existing Google search and YouTube alternatives that respect the user are niche. Only offline, self hosted models will be ad free (in my estimation).
