I worked for a company with a UK department, the UK boss would routinely use similar software to check that people where actually working and doing things correctly. The Scandinavian bosses opted to just trust everyone to do the right thing and people always would. Interestingly enough if was always the British employees who would do things like steal customer contact lists when they left or do deals on the side, so…
you took a different lesson away from that than I did - I was fully expecting you to say "and little wonder, seeing as how the company had set up an adversarial relationship with the British employees from the get go" rather than "I suppose they had a reason not to trust people"
My take away is simply that there's less trust in the British society as a whole and it's not necessarily a fault or problem isolated to a single company.
