Does the PBSA harm Welsh Broadband Infrastructure ?

Being a private sector thing, this was a new one on me.

The PSBA network (Public Sector Broadband Aggregation) is a Welsh Assembly Government led collaborative national communications service that, in conjunction with other major Welsh public sector organisations, has created a national information & communications platform to enable greater efficiency and collaborative potential, helping to support the delivery of improved services for the people of Wales.

So this the P.B.S.A. a good or bad thing? So far my answer is I don't know. I suspect that

1. It costs a lot
2. It improves the efficiency of those who use it
3. It is more secure than a Internet based service

but does it have a negative impact on the private sector business and consumer provision? Those who are able it use it get a very good service, and so is there then a mindset among decision makes in the public sector that network infrastructure is actually very good ? I don't know. I understand that the Welsh Government are not part of the network, they have their own. Interested if anyone has views on the external impact that these 2 networks have on infrastructure in Wales.
