Actually we see attempts to extend libpurple with many recent protocols. For instance telegram works on pidgin AFAIK, and I could recently see se a Tox plugin.

Clearly we cannot play a fair game with the closed whatsapp, but hacking cannot be stopped or forbidden.

After all, it was always like that. If you go back of 10 years al "regular people" had MSN and similar stuff, and we were IRCing. As a hacker, you migth feel sad, and think openness lost the war. IMHO the only difference is that nowadays we have much more "regular people" than before. They were simply sms-ing before they could access whatsapp.
