I understand that if some people have not got enough speed they may not want to use a VPN as it could make iptv unwatchable.This is largely because some iptv providers hawk their cheesy wares with 'no vpn needed' - even though a day later it may be needed.
Coupled with the fact that a lot of permanently baffled users think that putting a vpn into use will take a month of complicated settings changes and permutations when in reality it's about as difficult as drinking a glass of water.
Some of them have just paid for a 12m sub and when told they should use a vpn will happily pay for a different 12m sub rather than spend 5 minutes putting a vpn on the device.
It's like scrapping a car because the ashtray is full.
I have two suppliers I use a VPN on both I just dont want my isp to cop on I am watching IPTV
