You absolutely do need SDL, it's full of knowledge by humans from trial and error over years of using input devices in the real world.

Good point. I think it would be fixable by using the Change Time instead of the Modify Time, because that changes when moving the copy over the original.

Good news, I've been working an adding file content hashing to Ninja: https://github.com/ninja-build/ninja/pull/2735

That will fix the "switch branches back and forward" case :)

Audio APIs on Android are completely different than on GNU/Linux.

3D was also different (OpenGL ES vs OpenGL mess), only now it's starting to become kinda the same with Vulkan.

Nope, they are also available as they are Khronos standards for audio, and Mesa also does OpenGL ES.

Do you need a tutorial?

You mean OpenSL ES? Is anyone actually using that on desktop? On Android there's https://github.com/google/oboe.

While Mesa has OpenGL ES it wasn't always available (for example not all drivers are using Mesa).

Well if it's GPL without CLA and they accept outside contributions, they can't relicense / make it propriatary. Unlike with MIT.

Step 1: discontinue the public repository, step 2: sell access to your GPL codebase.

The GPL (and even the AGPL) doesn't require you to make your modified source code publicly available (Debian explicitly considers licenses with this requirement non-free). The GPL only states you need to provide your customers with source code.

Sure, but it also allows your customers to modify the source code you provided, and distribute/sell it. With MIT they can simply relicence it and sell binary-only versions. The open-ness stops at that point.

> Multiple citizens faced police raids, investigations, fines, or suspended sentences (jail risk if violated) for online posts calling Green politician Robert Habeck derogatory names like "idiot" or "moron," or sharing mocking memes [...]

The police raids were done because of the posted Nazi images, NOT because of the Habeck insults.

Sure thing, as long as it doesn't require any permissions. I have installed multiple apks on my phone from unknown people. Note that Google's requirement is also for completely permissionless apps like games.

Did your users really consider your app if it wasn't in the Play Store?

Fairphone 6 with /e/OS for example.

We can also do both, right? :)
