For iOS: I fully recommend Thunder or Memmy. Very complete (I’m not a mod so perhaps lacking there?).
For Android: Sync is just so perfect. Feels like Reddit before it was overtaken with low-effort Facebook exiles. Boost is great as well. I know there are tons of apps for Android in particular but both of those just feel right at home for me.
Look, this is nothing new. This is the government identifying 32 centers which can compete for grants to develop technology. This has been normal for the U.S. government our entire lives. This is, in fact, similar to how DARPA operates. This is why we have the modern internet.
