Pretty sure folks are referring to streaming sites meaning like Netflix. The person you are responding to said “click and go” referring to services like YouTube and Hulu not sketchy “streaming” sites like what you are describing that require some hoops to go through to make sure.you don’t download a virus.
I think there are many others one could point to more accurately, including Yahoo who purchased and then resold tumblr.
While Tumblr has made a lot of changes, some of which were walked back, they are still a well used and beloved site today. There are many now-dead or barely alive behemoth Internet companies that are better examples of “poster child for running a terrible Internet business” imo.
