As I’ve continued to repeat, a change in user preference (mostly from one ideology) is to blame for this.
Reddit went from pretty much complete free speech to one of the most censored websites in existence.
Huge portions of America now prefer censorship so Reddit has in essence created a moat for themselves.
If Americans were more accepting of all speech like before, Reddit clones would be easy to switch to. Now, you’re not only battling new censorship standards, but good luck getting on the IOS and Android store as a free speech forum.
On top of that, there are political benefits to this censorship. So that adds even more defense to the moat.
