Most of the "machine changed my vote" accusations have to do with touchscreen calibration and in many cases simply voter error. This is one of the reasons why the narrative of suspicious machines is so dangerous.

Could this be done maliciously? At least on some machines. But to allege that enough people were doing this to flip multiple states without detection is ludicrous. Hordes of people would be describing getting checkmarks on the wrong candidates. Examination of the machines by election officials would expose the conspiracy.
can be, not has been
Is it right to be worried about these issues and trying to make the system foolproof? Of course there is. But let's get a grip. It reminds me of the non-political hand wringing over the exposure of memory cache to programs that should not have access on Intel platforms running windows. A researcher proved that it was possible for a hack to extract meaningful information, some of which could be very sensitive data. But nobody had ever actually done it, it would require a massive amount of effort and technical sophistication.
All electronic and physical security is about making intrusion difficult - not impossible. And once you start to have a wholesale distrust for all elections officials, I'm not sure what system will keep you from claiming unproven fraud. Even if people were marking ballots with sharpies, you could blame the calculation machines, the operators of scanning devices, or just the reported precinct totals themselves.
Well reasoned and honorably posted. There are several responses to your statements of fact. Firstly, The machines can be programmed to cheat - either with simple thumb drives that can be plugged into the machines locally, or purpose-written script that can be hooked up remotely.
Here are some bits of info that may be interesting. The last one is particularly worthy to study as it comes from the Gateway Pundit.com which makes an effort to admit Conservative leanings - but insists all claims be transparent and well documented. Maybe someone here can explain why the Edison totals differ from the State totals. "The Edison state data supplied to the media and the county data supplied to the state don’t mirror each other and don’t agree until very late in the process – these results should mirror each other at all times accounting for timing issues".

"Government Admits Dominion Voting Machines Vulnerable to Hacking in 16 States.
Dominion voting machines have the potential to be breached, according to an advisory from the
U.S. Cybersecurity and Infrastructure Security Agency.
These, of course, are the machines that caused controversy in the 2020 election.
The Dominion machines are now shown to have nine vulnerabilities, according to the Friday advisory."

The CISA advisory is based on a report by computer scientist J. Alex Halderman of the University of Michigan. He has previously argued for multiple safeguards to be put in place for voting machines and has said that hand-marked paper ballots are the most secure way to vote, according to the AP.
Hartman noted that while it’s difficult to carry out a hacking, it can happen.
