You might as well say the same argument about Snapchat Inc. who is now known as Snap. Even more generic than 'Apple' as it is used as a verb, adjective and now a company name which appears at the top of the Google search results despite the founders launching their company as Snapchat Inc.
From a SEO point of view, The transition of 'New Vector' -> 'Element' is just as bad since the continuity of the name is completely lost and has to compete again in the SEO rankings.
The thing is with very generic names in search engines and word of mouth, continuity is essential and the creators of Riot have to rebuild it again with a generic name.
