I had this problem the first time using it, but once I learned about how to use homebrew with it (included by default now, by the way!) and distrobox with universal installer, I got a lot more comfortable with it!

Not that it absolves them of their bullshit, but you can set their router to bridge mode and use your own. It still removes the bandwidth limit.

It is a PITA to set up bridging though, thanks to their fuckery with the software. Fuck comcast
