I would actually be willing to pay a small, reasonable monthly fee to not have to see ads and to be able to continue using Boost for Reddit like I have been for the last 7 years with the experience unchanged. What I will not do is pay to use reddit's official app without ads simply because it's going to be the only choice with their horrible fee structure that will kill all third party apps. As soon as they kill Boost, my account there goes dark...
What I'd actually rather do is have all of reddit pay devs of a federated platform like this one or similar a small amount to have a platform without ads.
