It's absolutely insane to me how bad the user experience is with video nowadays, even video that's not encumbered by DRM or complex JavaScript clients.
A company can increase its profits (1) by improving their products and services, so that they'll get more customers or customers willing to pay more, or (2) by increasing how much of their revenue is profit by (e.g.) cutting corners on quality or raising prices or selling customers' personal information to third parties.
Either of those can work. Yes, a noble idealistic company might choose #1 over #2 out of virtue, but I think that if most companies picked #1 in the past it's because they thought they'd get richer that way.
I think what's happened is that for some reason #2 has become easier or more profitable, relative to #1, over time. Or maybe it used not to be so clearly understood that #2 was a live option, and #1 seemed safer, but now everyone knows that you can get away with #2 so they do that.
