Did all the eligible voters who phone-polled actually vote?
Did they poll the way they actually voted?
Some people don't have two phones?
Can we trust that telegram doesn't have a flaw in the means by which it is measured? (i.e. register again with the same SIM, or something like that?)
It's nice that there is a phone number as validation, but this doesn't 'prove' anything.
Edit: I should add, apparently people are registering photos of their votes, which don't jibe with the tally, which is probably a much better indication of problems with voting [1]
Whom exactly benefits from that? It would have to be a nation-state, and they weren't exactly doing much about the situation before the "election".
What is more likely: that the existing dictator and his supporters made defrauded the election to keep power or that some unknown entity defrauded an Telegram poll for not much gain.
Unless Telegram poll's system was completely broken, but you'd expect other large polls to already have revealed that.
Propaganda and narrative is the whole name of the game here.
It's Telegram poll, there are any number of ways it could be messed up, including very easily someone sympathetic at Telegram (though I doubt this), it has no material credibility.
It's a data point, not 'proof'.
