Very much this. The current outcome of any tenant complaint is a private warning not to make a fuss, with an auto-served eviction notice if the tenant makes a fuss anyway.
This situation can only be improved by legislating away at-will evictions (no, less demand would not help fix this, see pandemic). No chance of that in most of the U.S., though.
Uber/Lyft improved upon taxis because there were a lot of people who wanted to supply the service, but it was illegal for them to do so until Uber/Lyft punched a hole on the legal system. The rental market does not have this problem, in some sense the opposite.
