Apart from the fact that (using an iPad) I can't find Sky's upstream speed specified at all, and Terms & Conditions on the 38Mbps product page gives a mere two lines that tell me little useful, Plusnet are not cutting anyone's upstream speed. Nor are they reducing the upstream on the replacement product to ADSL2+ speeds. Exactly double, excluding the tiny proportion of ADSL2+ users who can get a significant benefit from Annex M -
at extra cost.
So whilst I accept your position, I don't accept the reasons you give.
There is no reason either why Plusnet 38/2 shouldn't sell perfectly well, just like it does on TalkTalk.
As for the support hours, which ISP do you understand ofers the best support? The general opinion seems to be AAISP. Have you looked at their support hours?
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
