I think it was a wise decision, as it will help Twitter to monetize its platform in addition to the ads it already sells. It will also help to ensure that only those who are truly dedicated to using Twitter will be verified, which will in turn help to improve the quality of content on the site. Furthermore, it will likely bring in a significant amount of revenue for Twitter, which can be used to improve the site in various ways. Bots will also be less likely to be verified, which will help to reduce spam on the site.
