We actually:
- have been friendly to 3rd party clients developers, like Loquim (https://loqui.im/). Once WA turned on e2e encryption, the situation for 3rd party clients changed from "difficult but fun" to "mostly impossible".
- wrote a JVM in JS to run the S40 version of WA (https://github.com/mozilla/pluotsorbet).
- partnered with a company specialized in bringing android apps to other OSes (they had Windows Phone support for instance).
