I wouldn't be surprised that is how they lost the majority of their user base. Everyone I know was on it, myself included, but once support was hampered around the time the AIM protocol died, most people around me left for Telegram and Signal.
IRC
ICQ
MSN
Yahoo messenger for some people in japan
Whatsapp, but noboday was there haha
Whastapp, some people there
FB Messenger
iMessage, but bugs with normals SMS, so disabled it
Google talk.. used by some, but I like to de-google a bit.
Back to whatsapp
kakaotalk, line, and wechat for research / gaming
Telegram. don't like it at all
Signal. kind of buggy
So in the end, I'm using whatsapp ads it's still ubiquitous here, and it's one of the most secure platforms.
Jabber a bit,
AOL Messenger,
Blackberry messenger,
Bloomberg Messenger (bank paid 2k per month for it!),
Skype for messaging,
Keybase (kind of cool but too heavy),
Slack,
and now Element Matrix.
Its one place sometimes I think regulation might be good to force standardization (like electricity or phone standards).
Oh and when I go to asia I use the ones there - viber, line, wechat etc.
IRC
ICQ
AIM
Trillian
Skype
Slack (just co-workers)
Discord (just co-workers that are friends now)
Must be like over a 30 year period of time.

It's amazing how much spinning happens in current media. The only people in the world who truly know how much this is are those who get the headlines before the stories are written and talked about, like day traders, who get it for speed reasons. It's cool, but it sucks it costs so much to get an unfiltered news source.
