Rogers does (did?) this too, though most people are now on their new &quot;unlimited&quot; plans so it hasn&#x27;t been a concern recently. (Funny how unlimited plans also avoid zero-rating net neutrality concerns for first-party or partnered services...)<p>Telus&#x2F;Koodo wireless has a proxy that at one point back in 2012 was incompatible with Chrome&#x27;s bandwidth saving features, at least back when I was testing in Canary. I was never able to follow up on said proxy after reporting the bug to Google, who got in touch with Telus, but ping times were at least 100ms higher in general than what Rogers Wireless was giving me for similar assets&#x2F;signal strength.
