After chatting to a few gen z, if I was to assume a characteristic of this generation, it's that most seem to have completely given up, or not even started, the fight against the deterioration of online privacy, exposure to ads, and companies "rights" and/or ability to harvest personal data from them no matter what they want. It's just part of life to them.

It's just accepted, and whenever I've raised the issue with them, they'll generally just reply with defeatist/pessimist/'pragmatic': "well, the alternative X, y and z apps/websites you've suggested likely all have hardware backdoors forcibly installed anyway"

So I think the willingness to fight, and picture a different way of having things, really is focused on those within millennial and gen-x age bands.

Edit: the point being, gen z therefore appear less likely to move away from existing structures, like Snapchat and Reddit, over increased ad promulgation, personal data harvesting, or bad company behaviour.
