This is an interesting and plausible narrative, but there's no reason to think that Javid doesn't believe that reigning in social networks is a genuinely good idea on its merits. Everything else you have said is interesting but irrelevant (when it isn't outright mind reading). Of more importance than the possible motivations and causes is whether this is a good idea, whether it will achieve its aims, and whether those aims are desirable.
