On the backend Parler was literally running on Amazon hardware and software. When Amazon evicted them they were offline until they rewrote their software to work on other infrastructure. At the same time Google and Apple banned them from their app stores removing them from mobile. They eventually came back but never recovered and were bought out and shut down.

Self host and use PWAs was the lesson there.
