no doubt they be doing that for a couple of years then just leave it. 
This quote from that web page:
"We have a three-year business plan that will change as VoIP technology changes. It is a fast-moving marketplace and
we do not have an exit plan, as too much will change in the next few years. Opportunities will determine our exit plan if we should require one. " .
I suppose that could be open to interpretation depending on how you read it.
Hopefully, if they are getting into telecoms, they will be subject to a regulator.
