But the reader should be aware that these writeups of how to do X often involve the writer/publisher getting referral kickbacks from the commercial service they're describing.

I'm about to be in a position of doing something like those writeups, as a microstartup, and I'm not entirely comfortable with the affiliate programs. But the companies monetizing with privacy-invading ubiquitous profiling trackers (sometimes euphemistically called "showing ads" and "analytics"), and otherwise selling personal data, have spoiled most potential willingness of readers to pay for content. So, affiliate programs with an obvious potential conflict of interest is the only way I've thought of to fund the work.
