I used to contribute to Exercism a lot (I'm still technically a maintainer but haven't meaningfully helped in a while), I think it was the first OSS project I contributed a large amount of effort to. I was more or less the sole maintainer for C++ for a while and also helped with the C track.
It's definitely a good service and OSS project, I recommend it a lot. Fundamentally though people don't want to pay for things that they can get for free, or they're used to getting for free.
If people actually want OSS projects to survive, you should be giving a little bit of recurring money. I set aside $XX/month to distribute to projects and I don't even work anymore.
