I can confirm that this works quite well. I use these tactics all the time on my parents’ feed to keep them from watching too many “crap” news, pardon my french. There’s a very notorious news channel in our country that insists on feeding bad (and only the bad) news - I often remove their channel from the suggested feed play videos of funny fails/wins, cute cats, daily dose of internet and other happy nonesense.

Been using Signal for a very long time now, with my SO, parents, brother and a few friends. But it’s inevitable to also use WhatsApp side by side. Selling/Buying on the local marketplace? WhatsApp. Workplace colleagues? WhatsApp. That group of buddies where only 1 or 2 converted to Signal? WhatsApp.
