Twitter deal on hold because on dispute on percentage of fake accounts

The billionaire Elon Musk was planning to take over Twitter but the deal is on hold regarding the percentage of Fake accounts. While the twitter ceo parag agarwal claims that only 5% of the twitter accounts are fake, Musk claims that more than 20% of the accounts are fake.
Since twitter did not agree to reduce the price, due to the high number of fake accounts, the deal is on hold.
Though twitter has so many fake accounts, it is able to charge a very high amount for each engagement of $1-4 while webmasters do not make $1 from advertising even after 3-4 months despite sending thousands of visitors.
