It does indeed help their portfolio but the statement that virgin was doing very well is more than questionable.
The last quarter saw an extremely aggressive retentions department trying to stop customers leaving as if their life depended on it. There are numerous reports of this and lies being told simply to stop customers from leaving. Experienced this first hand too and the lies virgin staff told was shocking. That same last quarter virgin moved the "Thinking of leaving us" option from their phone system and hid it away under "Thinking of moving house". That option had been in their menu system in the same place for years but hiding it away under an option you would not necessarily choose if you just wanted to terminate your connection was in my opinion desperation toi stop more customers leaving.
So tactics like that to make a quarters results look a certain way but the underlying problems are there still. Like the limitations of virgins broadband technology. Even talktalk offers a faster upload speed than virgin and I don't see virgin competing in a cloud environment future due to this. Already they are losing ground here and adding on more traffic management will push customers over to fibre alternatives like BT and Sky which have no traffic management or limits/thresholds or whatever.
The bottom line is taking quarter results as a sign that a company will do well in the future is just plain silly. You have to look at the whole picture. Look at how virgin have been broke and not able to invest in their network properly, look at how they have worded quarterly statements differently between quarters to hide worse figures, look at how the landscape is changing and where virgins weaknesses are.
Virgin were doing average at best. Without being brought out recently, I would have predicted them out of the game in around 2 years.
Even the biggest companies go out of business and up until that point they are trying to convince the world they are ok and doing well
