Sure, no problem. If you dislike systemd that much, it certainly makes sense to move to a different software platform.
I don't particularly dislike systemd per se. I do observe the controversy around it, and the image of it and its project, painted by its opponents (some of whom have enough creds that it's unlikely that they're talking through their hats), indicates that the claimed issues are likely to be real problems, and this may be a tipping point for Linux adoption and user choice among distributions or OSes.
Your Snowden argument isn't particularly applicable in this instance, as you have access to the full source code for systemd. If you're not comfortable looking through C code, then any init system would be a problem for you.
I did my first Linux drivers (a PROM burner and a Selectric-with-selonoids printer) on my personal Altos ACS 68000 running System III, wrote a driver for a block-structured tape drive for AUX - working from my own decompilation of their SCSI disk driver (since the sources weren't available to me initially), ported and augmented a mainframe RAID controller from SvR3 to SvR4, and so on, for nearly three decades, through hacking DeviceTree on my current project. I don't think C has many problems left for me, nor does moving to yet another UNIX environment - especially to one that is still organized in the old, familiar, fashion. B-)
As for trying to learn how systemd works, that's not the proper question. Instead, I ask what is so great about it that I should spend the time to do so, distracting me from my other work, and how doing this would meet my goals (especially the undertand-the-security-issues goal), as compared to moving to a well-supported, time-proven, high-reliability, security-conscious alternative (which is also under a license that is less of a sell to the PHBs when building it into a shippable product.)
Snowden's revealations show that the NSA, and others like them are adept, at taking advantage of problems in obscure corners of systems and using that obscurity to avoid detection. The defence against this is simplicity and clarity, avoiding the complexity that creates subtle bugs and hides them by burying them in distractions. Bigger haystacks hide more needles.
The configuration for systemd isn't buried. It's there for all to see and change, in plain text. Logging in binary form is _optional_. You can choose to direct logged messages to syslog, or use both syslog and binary, to have the "best of both worlds", albeit with the best of disk usage.
Unfortunately, I don't get to make that choice myself. It's made by the distribution maintainers. My choice is to accept it, open the can of worms and redo the work of entire teams (and hope their software updates don't break things faster than I fix them), or pick another distribution or OS.
Again, why should I put myself on such a treadmill of unending extra work? If I could trust the maintainers to mostly make the right choices I could go along - with no more than an audit and perhaps an occasional tweak. But if they were making what I consider the right choices, I wouldn't expect to see such a debacle.
Entangling diverse processes into an interlocking mass is what operating systems are all about!
No, it's not. The job of an operating system is to KEEP them from becoming an interlocking mass, while letting them become an interacting system to only the extent appropriate. It isolates them in their own boxes, protects them from each other, and facilitates their access to resources and ONLY their LEGITIMATE interaction wherever appropriate and/or necessary. The job is to Keep It Simple while letting it work.
Your phrasing, and making a joke of this issue, is symptomatic of what is alleged to be wrong with systemd and the engineering behind it.
