I agree with your second paragraph but the NHS is decades behind other developed countries in terms of digitisation and data use and this is not because of lack of investment. The longitudinal record alone has seen billions spaffed up the wall by many iterations of initiatives to restart the work.
The problem is not underinvestment nor is it evil big corps - its the structure and practices of the NHS fiefdoms who all want their own little empires and will not cooperate for the greater good. If Streeting can make progress on that it will be the least known but most valuable contribution to dragging NHS systems and processes into the 21st century.
All ministers and shadow ministers work with the private sector as they should. The private sector always has and will deliver goods and services to the public sector and sees much more innovation. People move both ways between public and private and for the most part the benefit flow both ways. Most don’t do the full Clegg and become seven figure salary apologists for big corporate greed.
I’ve seen some lunatic accusations that Streeting brought in Palantir - it was already there years before he took office since gove and Cummings were mandating its use across departments ten years ago. Presumably those posters would like Streeting to spend the NHS budget reversing out one supplier and moving to a new supplier of the same services.
