IMHO I think they would be interested based on the fact they offer a similar product right now as an add-on to their broadband deals.

For example: https://www.telstra.com.au/broadband/extras/broadbandprotect#social-network-protection

$9.95 per month.

But it's limited because it's only works for devices connecting through your home broadband router and I doubt whether there is any sophistication with it, it would using white/black lists and probably looking out for swear words and then relying on email based alerts. This would be easy to get around by smart kids - for example, why not use mobile broadband or a route diversion to avoid troubling your parents with an email to say you visited porn.

So WFI would fill the gap for Telstra or other telco customers using mobile devices to achieve their willingness to offer cyber security add ons. If the algorithms are good, as I suspect they would be, being based on TKI research, they would probably do a better job with detecting harmful/risky cyber use.

Telcos will always want to show, even if it's token like, gestures that they are being socially responsible - this would be a good corporate citizen thing.

But just my view and DYOR.
