I think (do correct if wrong!) the EU has approved an interoperability law for big tech companies? So it should be just a matter of time until you can switch messaging app and still be able to communicate with people on wa and big messaging apps
Ofc if all your friends all use whatsapp zuck will still be able to read all your messages and get your phone number via your contacts... so it's only a partial solution. Still better than nothing tho.
Theres also jak and daxter, i believe it was called openGOAL?
AFAIK european laws only allow to patent "inventions". Software is considered to be a series of "words" in whatever programming language you're using and, like sentences, it's not an invention and can't be patented.
On the other hand, software-assisted inventions can be patented as a whole.
With that said, software can still be considered a "work" protected by copyright laws.
