Session messenger app is shutting down
Session team announced on their "Donation" page that the app is to be shutdown in 90 days.

They claim to have received $65,000 total in donations, however this doesn't seem to be an accurate number considering Vitalik Buterin, creator of Ethereum - has donated nearly $400k alone a few months ago.
Some of my earlier thoughts on the whole communicator, and particularly it's management who was known to waste crazy amounts of money on essentially nothing. Not to mention that the people behind session ran at least 2 crypto currencies, which they pre-mined and sold to early investors for millions.

Sounds more like a fundraising tactic than a shutdown notice.
I do not think anyone will donate to keep it going, people on X aren't happy about lack of transparency about donation from Vitalik, and a multitude of other things.
Happy to be proven wrong though. They would need to continue receiving $100k+ per month to keep it afloat, it's how much they burn through.
