From what I understand, the sticking point is the total bot count,
and since ElMu can't produce a trustworthy/reliable bot count which differs from Twitter's (meaning, he can't defend his claims),
he appears to be switching to attack, trying to get data on how Twitter produces their counts, even though he can't convincingly articulate any issues with either it or the result.
The sticking point is that he put an offer in when the company was worth twice what it is today, so now he’ll try anything to wriggle out of his commitment
