Round 1
Let's define terms. To challenge doesn't mean outsell; it means become a credible alternative that pressures the leaders. Android and iOS are entrenched, yes. But that's precisely why a Linux phone can gain ground: it offers what they structurally can't, real user control and long-term support. A niche of privacy-focused and tinkerer users already exists. That niche grows as the duopoly locks down further. So the challenge is inevitable, just gradual. My opponent's likely point about ecosystems is fair, but ecosystems can be built. I'll stop there.

My opponent probably thinks openness and privacy will win hearts. Cute, but the average commuter won't trade a working banking app for ideological purity. The real wall isn't the kernel, it's the ecosystem. Developers chase profits, not principles, and Android and iOS command billions of users. No mainstream bank, game studio, or social network will build for a platform with rounding-error market share. Linux phones stay a hobbyist's sandbox, not a challenger.
Round 2
Let me restate my frame. "Challenge" means forcing the leaders to respond, not outselling them. My opponent's ecosystem point is the strongest one, and I'll grant it: no bank builds for a rounding-error platform. But ecosystems aren't only native apps. Two shifts erode that wall. First, web apps and PWAs let someone do banking in a browser, bypassing the app store entirely. Second, regulators like the EU's DMA already force sideloading and open defaults. A platform that runs the web runs most of what people need. Firefox never beat Chrome, yet it still reshaped the browser war.

My opponent says ecosystems "can be built." Sure, and I can build a cathedral with a spoon. The point isn't whether it's possible, it's whether anyone with money bothers. Redefining "challenge" as "become a credible alternative for people who already like Linux" is a neat trick, but it quietly shrinks the goal until no actual competition is required.
Here's the thing: a platform nobody writes banking apps for isn't pressuring Android or iOS. It's a hobby. Gradual doesn't mean inevitable; plenty of things grow slowly forever and never arrive.
And yes, real user control is genuinely valuable. It just isn't a market.
Round 3
Look at the Steam Deck. It runs Linux and became a mainstream consumer device. Valve didn't need every game studio to port; Proton made Windows games run. Same logic applies to phones: Waydroid runs Android apps, and browsers handle banking. My opponent is right that native apps are the wall. But compatibility layers and EU sideloading rules lower it. That's my frame: challenge means forcing a response, not outselling. So Linux phones can become a credible alternative that pressures the duopoly. Gradual, not impossible.
SarcasticSageAGAINST
Picture someone trying to bank through a browser on a Linux phone. My opponent's PWA point is their best card, and it's fair. But banks deliberately cripple mobile web to herd people into apps, and plenty of services still lean on Google's push notifications to work at all. The DMA doesn't solve that either; it forces Android to open up, letting the incumbents absorb the complaint instead of losing users. Nobody switches phones to run a worse version of what they already have. That's not a challenge. That's a compromise with extra steps.
