Because I frequently supply to the automotive industry, I fully understand all these issues. No matter how good many open source projects are, companies always have to face lawsuits and liability. That is why, no matter how good Linux servers are, factories use Microsoft servers. Regarding the responsibility for that software, if a problem occurs, the company that signed the contract takes on the liability. Ultimately, they shift the security responsibility to Google. It is unfortunate for open source enthusiasts, but if they do not restrict open source and an accident happens, the possibility of a lawsuit being filed against Volkswagen would be the real problem.
