Exit polls only indicate election fraud. For example, exit polls differed, by more than the margin of error, from official results in 17 states in 2004. In 16 of those states, the official results favored W over Kerry. In 15 of those states, the winner was changed. See the book Was The 2004 Presidential Election Stolen? by Freeman.
To prove election fraud, the gold standard is to have hand counted recounts of paper ballots. As I'm sure you know, Republicans demanded hand counted paper ballot recounts in 2020. The recounts, in several states, showed Biden gaining votes. The recounts proved that election fraud did not change the results of the 2020 presidential election. In 2016, hand counted paper ballot recounts were sought in three swing states, Michigan, Wisconsin, and Pennsylvania. Republicans fought tooth and nail against these recounts, and while the recounts were paid for, they were not done. Thus, there is no proof that election fraud did or did not change the results of the 2016 presidential election. There were no hand counted paper ballot recounts requested, or done statewide, in the 2024 election. Again, no one can show proof that the 2024 presidential election was not changed by election fraud, either by only one company, or more than one company.
And yes, there are a handful of companies that make machines to electronically count our votes. In individual states, more than one company may make machines that count votes. But only a few companies make these machines. Central tabulators take data from throughout a state and give a total count for a state. There is communication between these steps in the process. Any one company could cause a problem that changes the result of an election. You must be familiar with Volusia County, Florida, in 2000.

What happened in Volusia County doesn't prove that Gore won the 2000 election (the media recount did that), but it showed that errors in machine counted totals could easily change an election. A hand counted paper ballot recount is the only proof that machines did not change an election.
Certainly Republicans use more than one way to cheat and win elections. I assume you have read The Conyers Report. But unless we can prove that nowhere in the machine count any numbers were changed, as in Volusia County, then the possibility remains. As detailed by Election Truth Alliance on their website, Republicans may be controlling enough machines and/or tabulators and/or communication to spread out an alteration of in-person, election day results (as opposed to mail in or early voting). Whether this involves one company or more than one is immaterial, this indicates election fraud, and demands proof either way.
