I'm not sure if that explains why deleted messages from months ago are being resurrected. That would imply that there is a persistence framework that has multi-month readback capability.

The oldest message from the twitter screenshot looks ~8 days old.
In the second tweet the user says "3 chats before the outage and now 15+ or more chats which I deleted before the week or two."
Two weeks (and in screenshots, only 8 days shown) does not seem surprising. Especially given the increasing rate of internet shutdowns across the globe [1].
E2EE is too important to play fast and loose with.
[1] "In 2020, Access Now and the #KeepItOn coalition documented at least 155 internet shutdowns in 29 countries." (https://www.accessnow.org/keepiton/)
