The companies that list links to the Magic Quadrant have all paid a lot of money for this privilege. They also pay a lot of money for cross-marketing services that Gartner and the many brands (Capterra, SoftwareAdvice, GetApp, and more) they own provide.

Second, they make money by writing about hot topics like AI, ML, Big Data, etc., even when only 1% of BI implementations utilize these. Boring old BI best-practices (e.g. user adoption, semantic modeling, etc.) do not get much clicks.

With that, I do think the analysis is pretty good. Microsoft's ability to execute is solid, however I would say it's not visionary - there aren't many/any features that many of the traditional BI providers have. Tableau is awesome, but not "enterprise-BI", meaning there are few medium+ organizations that can use it as their main BI tool. Qlik has excellent ability to execute, but is really old tech under the covers. They were bought by private equity firms that are milking it's value until they retire it - oldest trick in the private equity book. Having used Yellowfin, it should probably be higher. Oracle should be dead last. IBM should be lower on ability to execute, but much higher on completeness of vision. One of my main critiques is that IBM Cognos tries to do too much, making it inaccessible to regular users.
