It’s important to differentiate between being a monopoly, and engaging in monopolistic behavior.
Valve, to the best of my knowledge, isn’t doing anything that prevents or stifles competition. As a monopoly it’s important to investigate them from time to time to ensure this remains true. But if they’re just putting out the best product and everyone is choosing to use them, then it’s not really a problem.



My immediate thought, there is no way Yahoo! Screen survived into 2019.
I looked it up and Yahoo! Screen (which featured Community season 6) was shutdown in January 2016. But Yahoo! View launched in late 2016 (as a Hulu-like replacement), and that did shutter in mid 2019.
So Yahoo! was already dead, but it also died for real in 2019.
