Not a geek but consider this: If the software was hacked, as alleged, whoever hacked it did a really poor job. If it were the republicans Trump would have won. If it were the democrats they could have taken the senate by storm, maintained their house seats and created a landslide win for Biden. Additionally if you bothered to do some research you would have found that Direct Recording Electronic voting systems are more prone to errors. These are the machines used when you go to a voting booth to vote and were therefore overwhelmingly the machines used in many voting locations. Since the initial results showed Trump wins on the contested states, seems like these were either hacked to favor Trump or they actually did record the vote correctly. Experts seem to agree that paper is the gold standard for voting because the paper ballots can be checked and audited, and even hand counted if there are questions about the technology. And then there is also this:
In Arizona results are stored on a server not connected to the internet.
"Arizona law prohibits voting machines from being connected to the internet. All elections systems are air-gapped, which means they are never connected to the internet or to other networks."

In Pennsylvania, " All certified voting systems in Pennsylvania, including the election management system and vote-tallying components, are never connected to or permitted on internet-facing networks, which significantly decreases opportunities to be hacked."

In Nevada, "The voting system is the equipment used to create ballots, cast and count votes, and display election results. Nevada's voting system is a "standalone system" that is not connected to a network, the Internet, and do not have wireless connection capabilities. Before any component can be used in Nevada's voting system, it must first go through a series of tests and audits. Additionally, each component maintains a chain of custody with tamper evident security seals and access limited to authorized personnel. The following documents describe these tests and procedures. Please refer to this narrative and diagram for an overview of Nevada's Voting System Testing and Security procedures.
