And stuff like Wikipedia which runs ad free off donations.

Honestly, I'm okay with that, most info I get is from Wikipedia, scientific papers or tiny random blogs. What sites are you afraid of it killing? Junk news sites? Reddit? I can live without them. I struggle to think of any with significant value.

If only one could use a normal news reader to access it.

Indeed - I think ad-paid centralization (largely for ease of use sake) effectively drove a lot of great stuff off the internet.
