How to persuade people around me switch to Matrix/Element?

Hello fellow c/privacy members.

I'm not new to privacy related things but I had a hard time persuading my family members and friends to switch to Matrix/Element. It is a reponse to UK's Online Security Bill and Investigative Powers Act that may soon in effect.

While it is just a preperation and planning in case those actually became law, I already face resistance from them. When I ask them would they switch, their first reaction is "Why one more app?" then follows with "That's cumbersome." or "I don't want to learn a new app." and suggest something more popular like Line, Telegram or Discord. Sometimes they would "Install WhatsApp because X is on there and he/she won't install one more app just for you."

What can I do to persuade them to use a new platform? Thanks in advance.

EDIT: I think I should elebroate more of what Online Security Bill and Investigative Powers Act does[1]. As far as I understand, OSB will break E2EE by require scanning data on client device, like CSAM but much more generic. IPA requires companies to submit security funcition to the government for approval before releasing, and disable such feature upon request. Apple[2], Single[3] and WhatsApp made the announancment of exiting the UK market totally or partically if two were signed into law.
