Does anyone have concerns about for profit technology companies using un-vetted software in tabulating election results?

Its seems that the Iowa caucus was hampered by the app created by tech company Shadow Inc. There were inconsistencies in the reporting of three sets of results yet all involved are claiming all is good. So far no evidence of a hack or other intrusion was found however curious what data was collected by the app other than voting results. One can't help to wonder if the app is capable of data mining like that of the Facebook's Cambridge Analytica scandal. Just feel if a for profit is collecting data seem possible such data could as well be sold to the highest bidder or even giving to political parties. This data then could be used to target individuals with political ad campaigns with the intent to persuade voters to vote for a particular candidate. While voters would still be the one voting, who they vote for could possibly be manipulated. One has to look no further than Cambridge Analytica to understand the ramifications in alloying private companies access to data points and attempts of social engineering via political ad campaigns and the ability to influence elections.
