Frictionless fragmentation would be that services adhere to some standard API and that viewing tools (we optionally build ourselves) can simply sign in to an arbitrary list of services. If that were possible, then yes.
For many streaming service, I can't even figure out if the support Linux (e.g. HBO does not explicitly state I can use their service with a browser on Linux). So, it makes no sense to sign up even if I thought it was worth the money.
They 'guarantee' things work on particular browsers on particular OSes, not on 'modern web tech'. Well, I'm not going to spend money on something that has no legal guarantee or even promise to work.
Web browser is the standard API. And the viewing tool is Windows.
I know you wanna plug in your $20 to $50 dongle into an HDMI port and hope for the best, but your laptop will work fine, and I'm pretty sure your phone (Android / iOS) will also work fine.

Well there's another problem. Linux isn't a standard (Debian, Fedora, CentOS, Ubuntu all have different quirks). By the time we start looking at those weird hardware codec accelerators and whether or not Linux supports those drivers, you would have been done with your Windows + HDMI port.
