Not every app on Linux is compiled for MIPS, or am I wrong? I mean, technically Windows 8 RT could run natively on ARM without problems, except you couldn’t run any apps, which made the whole thing 100% useless.
Unless every app can run natively, you’ll always have to run some sort of translation layer, either in software, hardware or both. That layer will have native performance.
I can understand if someone like Google or Microsoft employs lawyers directly, as they have the resources and scale to do so. But someone like Telegram should really not do that. They should use an external legal office when needed. Even keep them on retainer, but definitely not open a legal office inside the company.
