That is not an NDA at all then! A very different contract and you are absolutely right to refuse signing it. The company is totally acting outside of a normal legal practice, worth suing.

Been there. What is the problem with signing it and getting the cash if you are not going to sue the employer?

By the way, installing Adguard (or something similar to cut out ads device-wise) helps to decrease the shit they are trying to install dramatically. Highly recommend. Family link works for me so far, though the kids are a bit younger.
