It just has a different owner, and the prior owner (the Graham family), while not as rich as Bezos, was still plenty rich. Don Graham famously tried to invest in Facebook as early as 2005: https://www.forbes.com/sites/jeffbercovici/2012/02/02/facebo...
Bezos, while involved, has not changed the basic tenor of its journalism beyond maybe souping up some of its technology. Also, WaPo publishes pieces critical of Amazon and its subsidiaries all the time:

https://www.washingtonpost.com/business/economy/whole-foods-...
(Also, but on a different note, GigaOM was sold off because it had previously shut down and laid off all its writers.)
I'm 100% pro-Bezos buying WaPo, especially since it seems he hasn't touched the editorial side of things. BUT it has been used to discredit legitimate WaPo journalism by Trump ("Amazon's Washington Post" / "Bezos Washington Post" / etc)
I included GigaOM because it's probably closest to Gawker (relatively small blog, shut down due to external forces, and brought back with a new name).
I didn't mean to imply all of these were nefarious changes. Rather, they're examples of people hijacking well-trusted (or well-known) brand names, which in the world of blogs/twitter/rumors are hard to come by.
