I want to know currently who has the rights over the WP.
Nobody. It's open source.
This option seems to me the most acceptable for a decentralized system in which there is no big boss, where the network simultaneously "belongs to everyone" (the right of everyone to use it) and at the same time "to no one" (the absence of a single center and owner). If someone had ownership of WP, that would be a contradiction. I believe that WP belongs to everyone (everyone has the right to access this information) and at the same time to no one (there are no specific personalized rights holders). I dare to say this: WP, like bitcoin, belongs to the crypto community - both to everyone and to no one personally.
