I suspect that a significant underlying (ie unspoken) motivation for the bill is to create an environment in which ordinary people know their place because they know they can always be watched. Preserving the status quo that keeps the UK a profitable place for some, while emiserating large parts of the population, requires this. The recent legal changes that criminalise peaceful protest are part of the same pattern. They can see social fracturing coming in the near future - due to austerity, economic mismanagement, climate breakdown, etc. - and they're getting their retribution in early.
