Confirmed my suspicions. FWIW in SW Florida after severing Xfinity TV service ties, the replacement with ROKU boxes, et al, DID result in significant throttling of internet connections even after the speed increases were announced by Xfinity. The home 'Blaster' package saw a reduction in large .mp4/.zip file download speeds from 12MB/s to 5. That was coupled with frequent connection drops while viewing ROKU content. And you could forget about 4K content. Miraculously, when an Xfinity app was installed on ROKU which required a supplemental CATV account, which conveniently Xfinity marketed at a 2 yr. super discount to undercut the DirectTV app package, the internet speeds increased from a throttled 5 to a consistent 15MB/s on non-VPN downloads (using IDM on Win7, similar results in Linux Mint). And 4K viewing was practical. Amazing! /s
