I think you should try a few different things out before you judge all software engineering jobs. There's a big variety.
As for "making shitty bloated proprietary software" that only really applies to the really big tech companies and banks etc.. Most dev jobs are about using code to solve a problem. I've worked in lots of small companies and we use open source software almost exclusively. If there's anything you write that you think could be useful as an open source project, they'll generally let you spin it out into a standalone library and you can spend some of your working time on that. The company benefits from increased visibility and can be a "thought leader" at conferences etc if it takes off. Definitely worth asking about that in the interview though, since different companies will have different philosophies around it.
Often you get all three about the same company
I think eliminating voting rights for citizens without children is a fascist policy. Fascism is about enforcing a "correct" or "natural" hierarchy in society. Historically this has usually been about race, but has also included other factors (for example, disabled people were the first group targeted for extermination by the Nazis). For some of us, not having kids is a choice (and imo a valid one that shouldn't be punished by the state). But this sounds like an easy way to discriminate against same-sex couples, and all fascist systems have a history of doing that.
Higher-level languages compile (pretty much) reproduceably into machine code, so the same C code would always produce the same executable as long as the same compiler version is used.
Current AI chatbots will produce completely different results if given the same prompt twice. In its current form it can't be used in a reliable toolchain for anything.
