Since it is a decentralized network they are literally forcing the client-developers to ban gab from their apps or else get them de-platformed from the app stores of Google and Apple.
Some apps with spineless developers with fascist tendencies complied, some others didn't and these ones i believe need to be rewarded.
One in particular (Fedilab) stood for free speech and against censorship and for this reason the free version of their app got deplatformed from the Google Play Store. You can still buy the full version (and by doing so show your support to the developer) here:

If you do, make sure to write the reason why you are buying it in the comments section of the app in the play-store so that everyone will see it, including the spineless developers that opposed free speech and the retard fascists that are pushing for censorship.
Personally i have bought it even if i don't really use gab nor the mastodon's fediverse just to show my appreciation to someone that stood for free speech even at the price of losing their "free" app (which i suppose had ads) from the play-store.
