Sometimes it's needed for other needs too, in my experience some will just blurt how complicated is to move or they will move but sometimes forget to open it to check for messages since they'd only be using it to talk to you instead of switching entirely to another platform like you did, some people are fine with the cost of isolating themselves to not worry of those who won't put effort to contact you through your privacy-wise better alternative you are using but some will eventually burn out and give in to partially going back to said terrible platforms like Discord, it's all about threat model. I find it easier to convince people from Discord to use Matrix but people using WhatsApp? Oh well, those you hardly will manage to convince them all for you to just quit it. How I see is in the end we are all different with different needs, some people will just happily comply with your request becauss they proudly will support you switching elsewhere for a reasonable and good reason but some will try and stop, and some will just keep insisting for you not to leave (then if you leave even if they're insisting you not to, who would be at fault then? they'd be begging you to stay and most of the time these people are usually the ones who still hasn't awakened to the dangers of privacy invasive platforms and just shrug it off, so they are not leaving because they don't care about you, they just don't get at all why you are doing it and find it pointless - which helps when you try to inform them in a long period of time about such things, but who does that all the time when trying others to switch? some find out about these issues and just want to snap into the better privacy-wise alternative asap)
FYI my reply isn't some defending talking points not to switch but to explain from different perspectives why some just won't bother
but its more of a simple definition however if you went more technical by biology and chemistry laws, wetness is about adhesion (liquid to solid surface contact) and water is cohesive (attracted to each other) but if you want to get reallyyyy into it you might tell me about mercurium, have you seen mercurium? because its freaking cool btw chemistry ftw

the reason why mercurium wont wet things is because its cohesion is stronger than its adhesion, so any liquid that happens to be like this, this is why
no, if water was just hydrogens yes but no because then its no longer water but with the oxygen the water molecules are not exactly touching each other plus the definition of wetness is about the adhesion (liquid to solid surface contact) and water is cohesive (attracted to each other)
actually water molecules are cohesive (attracted to each other, yes in that sense you are right) but wetness is associated with adhesion which basically means the possibility of a liquid to adhere to a solid surface so no, water molecule themselves alone are not enough to fit into the definition of wetness i hope i wasnt too technical but i tried to be as dummy as possible
