Tell that to my school division’s IT department, who have us all running Displayport to VGA adapters, attaching to our monitors and projectors via VGA. This is because our displays are either a) too old and only support VGA and DVI in, or b) they purchased displays with HDMI, but our ThinkPad laptops only have Displayport out.

Sometimes it is more a matter of mixing and matching tech in large cash-strapped systems that might get slapped by these issues as well.

And yes, those adapters cause as many headaches as you might think.

They already have. Why do you think grocery prices have been a major political talking point? Since most people don’t have enough money to buy property where they can grow/raise their own food, and many municipalities explicitly ban the raising of animals to “protect” the agriculture industry, most people are stuck. Your only option is the monopolistic grocery chains.
