Maybe something like how Wikipedia or PBS does it (without the days long membership drives). Voluntary contributions, but everyone gets full access. I’m not sure it the ads are just to cover operating costs or if it’s a for-profit venture. Either way, I’d have no problem contributing. I’d also remove the ad blocker if the ads were limited in location as they were before. I’m not asking to get something for nothing or to have someone else pick up the tab.
