It's as if they're counting how many more votes they have left to count, and then for each newly counted vote publish the new totals. Why don't they just wait until they're done counting, and publish only the final total?
It now seems like they're asking for attention for days, while they have no final data to publish.
You have to consider there are hundreds or even thousands of polling locations in each state, they have to open hundreds of thousands or millions of mail in votes, if it's close they have to verify thousands of individual provisional ballots (often times having to reach out to the voter to verify something), and in most cases they aren't even allowed to begin the process until election day (even though people have been voting for months).
They release whatever info they can when they can because literally the entire world is wants to know and keeping anything secret is a bad look. There's probably some National Security reason as well, the longer we go without knowing who the president will be, the more exposed to foreign threats...I'm just making that up, but it makes sense.
