I wouldn’t trust them to not randomly enable WiFi, but you can also use their modem but disable any built in WiFi on it & still use your own router. ISPs continue to try to bundle their modem & router, which gives them complete access to your home network. Some lucky people have found fiber providers that let them use their own SFP.
I think recent polls suggested it was about 50/50 that support what Israel is doing. It was around 80% at the beginning of the war, so many have come a long way. Honestly, sort of similar to the American support of the Iraq War.
