TouchArcade mentioned the answer to that question yesterday in their Game of the Year article:
Before we get to that though, I’d just like to take a minute to shout out to everyone who supports us on Patreon and have shopped through our Amazon links this year. When Apple killed the App Store affiliate program earlier this year, that left those two things as the only things still keeping us afloat. If you’re not a Patreon person and/or don’t shop through our Amazon links, we’d really appreciate it if you’d check the above links out, particularly if you feel like you’ve gotten any value out of TouchArcade’s continued existence this year!
I wonder if TouchArcade will survive 2019. Apple cut the affiliate commission rates in 2017, but now they are completely gone, as of October 2018. TouchArcade mainly covers games of little interest to me, but that’s more a function of the games that are popular on the mobile platform now, rather than a decision on their part to ignore what I prefer.
I don’t know how true it still is, but I enjoyed the fact that devs would participate in their forums. I recall that it was there that I learned from the developer of the difficulties in working with Apple’s implementation for sync’ing Guild of Dungeoneering between iOS devices, for instance. That’s one of the reasons that I’m a minor Patreon there, as well as here.

Unfortunately, after ten years of hard work there just doesn’t seem to be a business model that works for third party editorial to survive in the booming economy of mobile games.
