Anti-cheating software is a fundamentally flawed approach. As remote education becomes more common educators should leave the concept of an "exam" behind and embrace project-based and open book curriculum.

Art school is a series of project-based classes that culminate in a portfolio of original work that the student can showcase, and that system seems to make perfect sense to everybody.

I don't know why other disciplines have been so resistant (forget textbook publishers, I mean the professors, deans, and other administrators themselves.) It's not clear to me there are any reasons to be against it, so perhaps it's simply the inertia of large, bureaucratic, conformist institutions.

We can try to do that for computer science but it wouldn't work superwell because I feel like some fundamentals are core and needed a systematic way of testing

Totally agree, and this kind of solutions only blocks the laptop but the students can use their smartphones to search for the answers.

I feel like the reason there is a demand for applications like this is not to prevent all cheating but to enable the school / Uni to claim that anti cheating measures where used for online testing.

I think the product is really smart.
