One can only hope there'll be a watershed moment like the one that killed Digg. So far, reddit has been very careful raising the temperature so as to not scare the frog before it's dead.
Because they aren't having to pay for hosting.
The only way to replace reddit is with a distributed system like aether: https://getaether.net/
Or if you absolutely want a centralized system, something community run like ao3: https://en.wikipedia.org/wiki/Archive_of_Our_Own
But given the absolute hostility and hate _users_ of reddit give those two sites for not banning everything they find offensive a site like reddit is just not possible any more.
