apkpure contains the Parler apk that can be downloaded on any Android device. However be warned that 3rd party downloading is at your own risk (I have downloaded other apps before from it but not Parler)
Still no visual on apkmirror. No one loaded it onto there yet
AWS will deplatform them entirely soon probably. Thats what happened with Gab. Gab had to buy all their own servers to survive.
Buying servers are not only expensive but eat watts for breakfast. People will need to hire technicians and other data guys to make sure physical servers dont go to hell. Deplatforming is not only just to get away from the name, its to end an idea.
