> a major concern for not only the future of this platform but also for several industry-scale information retrieval systems such as Siri, Alexa which depend on Wikipedia as knowledge store.
That doesn't imply that the paper is advocating for it, but given that Apple and Amazon now have built products on top Wikipedia, their bottom line depends on it. It's entirely reasonable to wonder if they would prefer to have more influence and control over it. Whether or not it was ever a good idea for Alexa and Siri to have a dependency on Wikipedia is a moot point. They do now, and it wouldn't surprise me to see them wanting to take an active part in keeping Wikipedia fresh.
Of course, because their revenue depends on it, they probably would want more control. In the same way the Amazon is working to exercise more control over the Rust language, Apple or Amazon could decide that taking over Wikipedia is the right move to protect profits.
