There liberapay (patreon alternative) and mitra (patreon paywall alternative). there is also a peertube plugin.
Other then that having something that can show ads on videos but with an option to disable ads with pay (something like youtube premium), could be useful,
it's not that transparent , for example if i am considering funding signal , i can look at the 990 form , see the top salaries, the amount spent on salaries, the number of employees and calculate the average salary. I don't mind it if the shareholders make a 10-20 percent return but i don't want to to be a 90 percent return (which basically no public company has, from what i have seen in tech companies it is somewhere around 10-30 percent).
