Not applicable to Telegram, but if the app is open source and you have a Mac (!) you can install it using Xcode.

Since Signal is actually open source, you can install it even if Apple decides to block it in the future (if you have a Mac).

Telegram clients are open source and can be built yourself.

Kinda. They're open source, but the source code is not updated frequently.

This is a great option if your audience has very high need, but it will not make it available to the average non-tech savvy person who needs it.

OK, but High Sierra VMs in VBox are pretty easy with vagrant. Plus the standard tweaks for running on Windows and Linux hosts.

So technical users could install for their friends.

Do note that it will only run for 7 days unless you pay Apple $100 a year for the privilege of running code on your own device.

You can reinstall it every 7 days for free though!

This is only true for iOS apps, not for Mac Apps. You can get Xcode and compile whatever you want with it.

[gergles]

OK, but we're clearly talking in the iOS context, given that was the only platform Apple was blocking.
